Service tax was first introduced in India during the financial year 1994-95, specifically through the Finance Act of 1994. Initially, it was levied on a very limited number of services, namely telephone services, general insurance services, and stockbroking services. This marked the beginning of indirect taxation on services in India, which later expanded significantly to cover a wide range of services before its eventual subsumption into the Goods and Services Tax (GST).

Explanation

Convertibility of the rupee refers to the ease with which the Indian rupee can be exchanged for foreign currencies and vice versa, without significant restrictions, at market-determined rates. This concept applies to both current account transactions (related to trade in goods and services, remittances) and capital account transactions (related to investments, borrowings). Allowing this free exchange facilitates international trade and capital flows, integrating India's economy with the global financial system.

Explanation

Based on the gross tax revenue collections for the Central Government around the financial year 2014-15, Corporation Tax (I) was consistently the largest contributor. This was followed by Taxes on income other than corporation tax (II), which includes personal income tax. Union excise duties (IV) typically ranked third in terms of revenue generation for the central government, while Customs duties (III) usually accounted for the smallest share among these four major sources of tax revenue. Therefore, the descending order of gross tax revenue contributions was Corporation tax, Income tax, Union excise duties, and Customs.

Explanation

As per the Micro, Small and Medium Enterprises Development (MSMED) Act, 2006, the investment limit for medium enterprises in the manufacturing sector is defined by their investment in plant and machinery. For this category, the investment must be more than T 5 crores but should not exceed T 10 crores. This classification was in effect up to 2015.

Explanation

Infant Mortality Rate (IMR) is a crucial health indicator that refers to the number of deaths of children under one year of age per 1000 live births in a given year. It specifically measures mortality occurring before a child's first birthday, not their fifth birthday.

Explanation

India's trade balance has historically been largely in deficit. However, there were a few years where the trade balance was favourable, meaning exports exceeded imports. Among the given options, the years 1972-73 and 1976-77 witnessed a trade surplus for India, making the trade balance favourable.

Explanation

The chronological order of the given agreements by their signing/operational dates is as follows: The South Asian Preferential Trade Arrangement (SAPTA) was signed in 1993. The India-Sri Lanka Free Trade Agreement (ISLFTA) was signed in 1998. The South Asian Free Trade Area (SAFTA) was signed in 2004. The Comprehensive Economic Cooperation Agreement between India and Singapore (CECA) was signed in 2005. Thus, the correct sequence is IV-I-II-III.

Explanation

The annual average growth rate of agriculture and allied sectors in India at constant prices generally remains positive, although it can fluctuate due to monsoon variations. However, during the year 2002-03, India experienced a severe drought, which led to a significant contraction and a negative growth rate for the agriculture and allied sectors.

Explanation

Varsha Bima, the rainfall insurance scheme designed to provide protection to farmers against adverse weather conditions, is indeed managed by the Agriculture Insurance Company of India Limited (AICIL). This company is a specialized insurer for agricultural risks in India. The scheme was initially introduced as a pilot project in 2004, not during the 2007 south-west monsoon period as stated in the second statement. Hence, only the first statement is correct.

Explanation

Statement I is incorrect because the Bank Rate is the rate at which the Reserve Bank of India (RBI) lends money to commercial banks, primarily for long-term purposes, without requiring any collateral. Short-term borrowing is typically managed through the repo rate or MSF. Statement II is also incorrect because the Repo Rate is the rate at which the RBI lends funds to commercial banks for short-term periods, typically overnight, against the collateral of government securities. It is used for short-term liquidity management, not long-term borrowing. Since both statements incorrectly define the terms, both I and II are incorrect.

Explanation

Financial sector reforms in India, initiated in the early 1990s, encompassed a wide range of measures aimed at liberalizing and modernizing the financial system. These reforms included the lowering of the Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR) to infuse liquidity and improve credit availability. The entry of private firms into the insurance sector marked a significant step towards increasing competition and efficiency. Furthermore, the deregulation of interest rates allowed market forces to determine lending and deposit rates, enhancing the autonomy of financial institutions. Therefore, all the options listed are integral components of India's financial sector reforms.

Explanation

Bharat Nirman was a flagship program launched by the Government of India in 2005 to develop rural infrastructure across six specific areas. These components included rural housing, rural roads, rural water supply, rural electrification, rural telephony, and irrigation capacity creation. Agro-based industries, while important for rural development and often supported by other government schemes, were not explicitly identified as one of the six core components of the Bharat Nirman program itself. Therefore, agro-based industries is the correct answer as it is not a direct component of Bharat Nirman.

Explanation

According to the Planning Commission of India, based on the methodology recommended by the Tendulkar Committee (report 2009), the poverty lines for 2011-12 were fixed at Rs 816 per capita per month for rural areas and Rs 1000 per capita per month for urban areas. Converting these monthly figures to per day values gives approximately Rs 27.2 for rural areas and Rs 33.33 for urban areas. Among the given options, Rs 26 per capita per day in rural areas (Statement II) and Rs 32 per capita per day in urban areas (Statement III) are the closest and most commonly cited rounded figures representing these poverty lines for that period. Therefore, statements II and III are correct.

Explanation

The schemes listed have the following launch years: TRYSEM (Training of Rural Youth for Self-Employment) was launched in 1979. RLEGP (Rural Landless Employment Guarantee Programme) was introduced in 1983. JRY (Jawahar Rozgar Yojana) was launched in 1989. EAS (Employment Assurance Scheme) was launched in 1993. Therefore, the correct chronological sequence is II-IV-III-I.

Explanation

The National Agricultural Policy was launched in 2000. The Marine Fishing Policy refers to significant policy discussions or frameworks around 2004, though a comprehensive National Policy on Marine Fisheries was formalized later. The New Foreign Trade Policy (FTP 2014-19) was announced in 2014. The Seventh Finance Commission was constituted in 1977 and submitted its report in 1978. Matching these, we get A-3, B-1, C-4, D-2.

Explanation

The Pagal Panth was a semi-religious and semi-political movement founded by Karam Shah in the Mymensingh district of Bengal (present-day Bangladesh) in the early 19th century. His son Tipu Shah later continued the movement, which eventually evolved into a peasant rebellion against the oppressive practices of the zamindars and the British East India Company.

Explanation

The Farazis were a powerful Muslim reformist movement that emerged in East Bengal in the early 19th century. The movement was founded by Haji Shariatullah, who preached strict adherence to the fundamental tenets of Islam and advocated against un-Islamic practices. After his death, the movement was led by his son, Dadu Miyan.

Explanation

The Ramosi Uprising refers to the rebellion of the Ramosi hill tribe, led by Chittoor Singh, against British rule in 1822. This uprising took place in the Western Ghats region of Maharashtra. The Ramosis, who were traditionally guardians of forts and police, revolted due to unemployment and grievances related to land revenue assessments.

Explanation

The Wagnera Uprising, sometimes referred to as the Waghera Rebellion, took place in the early 19th century in Okhamandal, a region then under the control of the Gaekwad ruler of Baroda. The Waghers were a community in this area who revolted against the oppressive taxation and administration of the Gaekwads of Baroda. Therefore, the uprising happened in the region associated with Baroda.

Explanation

Several acts were passed by the British government in India to control or regulate the press. Key among these were the Press Act of 1835 (also known as Metcalfe's Act, which removed some earlier restrictions but was still an act governing the press), the Press and Registration of Books Act of 1867 (which imposed regulations on printing presses and publications), the Vernacular Press Act of 1878 (a highly restrictive act aimed at censoring the Indian language press), and the Newspaper (Incitement to Offences) Act of 1908 (which empowered authorities to confiscate property used for seditious publications). These years are accurately listed in option A.

Explanation

The split in the Indian National Congress, notably the Surat Split of 1907, was a culmination of deep ideological differences between the Moderate and Extremist factions. These differences encompassed divergent strategies for achieving self-rule (constitutional agitation vs. passive resistance, Swadeshi, and boycott), varying objectives (Dominion Status vs. complete independence or Purna Swaraj), and differing views on the participation of the masses (elite-driven movement vs. mass mobilization). Consequently, all these factors contributed to the eventual schism within the Congress.

Explanation

The series of articles titled 'New Lamps for Old' was penned by Aurobindo Ghose (later known as Sri Aurobindo) and published in the 'Indu Prakash' journal between 1893 and 1894. In these articles, Ghose critically analyzed the methods and policies of the early Indian National Congress, arguing that its moderate, elitist approach and reliance on petitions and prayers were ineffective and detached from the aspirations and struggles of the common people, or the 'proletariat'.

Explanation

The Nehru Report was an important document in India's struggle for independence, drafted in 1928. It was the outcome of a committee appointed by the All Parties Conference, which was tasked with outlining a proposed constitution for India. This committee was prominently headed by Motilal Nehru, with his son Jawaharlal Nehru serving as the secretary. The central subject of the Nehru Report was indeed the constitutional arrangements for India, proposing dominion status with a federal structure and fundamental rights.

Explanation

Katherine Mayo's "Mother India," Aldous Huxley's "Jesting Pilate," C.F. Andrews' extensive writings, and William Digby's "Prosperous British India" were all influential works published by foreign authors or observers. While their perspectives and sympathies varied greatly, the common thread among them was that they each penned significant commentaries, reports, or observations on the social, political, and economic conditions prevailing in India during the period of British rule.

Explanation

The powerful and iconic lines "Sarfaroshi ki tamanna ab hamare dil me hai/ Dekhna hai zor kitna baju-e-qatil me hai" are famously associated with the revolutionary Ram Prasad Bismil. Although the original ghazal was penned by Bismil Azimabadi, it was popularized and frequently recited by Ram Prasad Bismil, especially during his trial and execution, making it a rallying cry for the Indian independence movement.

Explanation

Maulana Hasrat Mohani, a prominent freedom fighter and poet, was the first to propose the demand for 'Complete Independence' (Purna Swaraj) for India. He did so by moving a resolution at the 1921 Ahmedabad session of the Indian National Congress. This significant demand predated the more widely recognized Purna Swaraj resolution passed under Jawaharlal Nehru's presidency in 1929.

Explanation

The Communist Party of India (CPI) was officially founded on 26 December 1925 in Kanpur. The Rashtriya Swayamsevak Sangh (RSS) was founded earlier in the same year, on 27 September 1925, by K. B. Hedgewar in Nagpur. Therefore, both organizations were established in the year 1925, making option B the correct match for their founding years.

Explanation

Swami Sahajanand Saraswati was a pivotal figure in the peasant movement in India. He founded the All India Kisan Sabha (AIKS) in 1936, which demanded significant agrarian reforms including the abolition of the zamindari system and the nationalization of land and waterways. This significant period of his organizational efforts and the formation of this key peasant body clearly falls within the 1930s.

Explanation

The Bengal Tenancy Act was passed in the year 1885. This landmark legislation aimed to define and regulate the rights and obligations of tenants (ryots) and landlords in Bengal and Bihar. It provided greater security of tenure for cultivators, offering protection against arbitrary eviction and enhancing their occupancy rights, thereby addressing widespread agrarian discontent and unrest prevalent in the region.

Explanation

The Third Round Table Conference was held in 1932, specifically from November 17 to December 24. The First Round Table Conference took place from November 1930 to January 1931, and the Second Round Table Conference was held from September to December 1931. These conferences were convened by the British government to discuss constitutional reforms in India.

Explanation

During the Non-Cooperation Movement, particularly in rural areas like Bihar, Mahatma Gandhi was often revered as a spiritual and moral leader, a 'Mahatma'. Popular beliefs attributed victory to him because he was perceived as an epitome of Dharma, embodying righteousness and truth. This belief system implied that his moral force and adherence to righteous principles would inherently lead to the downfall of the unjust British rule, rather than merely political maneuvering.

Explanation

Swami Vidyananda was a significant peasant leader who organized the peasants of Darbhanga district in Bihar against the oppressive practices of the Darbhanga Raj in the early 20th century. Swami Sahajananda Saraswati was another towering figure in the peasant movement from Bihar, who founded the Bihar Provincial Kisan Sabha in 1929 and later the All India Kisan Sabha in 1936, advocating for the rights of farmers. Sardar Vallabhbhai Patel was a prominent peasant leader, but his primary area of activity was Gujarat, notably the Bardoli Satyagraha.

Explanation

Rahul Sankrityayan, a renowned scholar and nationalist, was actively involved in the Non-Cooperation Movement of 1920-22. He played a crucial role in mobilizing the masses and spreading the message of non-cooperation in the Chhapra (often referred to as Chhappa) district of Bihar. He organized peasants and participated in nationalist activities in this region, contributing significantly to the movement's outreach.

Explanation

During the Great Revolt of 1857, many Indian rulers and zamindars sided with the British to protect their own interests and privileges. The Maharajas of Darbhanga, Dumraon, and Hatwa, along with several other prominent landlords in Bihar, were among those who displayed loyalty to the British East India Company. They provided crucial support to the English by supplying both men and money, which significantly aided the British efforts in suppressing the rebellion and maintaining their control in the region. Their assistance was instrumental in preventing the revolt from gaining wider traction in these areas.

Explanation

Peer Muhammad Moonis was a prominent journalist and social worker from Bihar who played a crucial role in bringing to light the severe exploitation faced by the indigo peasants in the Champaran district. Through his powerful writings, often published under various pseudonyms such as 'Dukhi', 'Dukhi Atma', and 'Dukhi Hridaya', he eloquently described the plight and suffering of the ryots under the oppressive tinkathia system. His articles significantly raised public awareness about the injustices in Champaran, thereby contributing to the background against which Mahatma Gandhi launched the Champaran Satyagraha.

Explanation

To find the value of f(f(5)), we first need to evaluate f(5). The function is defined as f(x) = x² - 3x + 2. Substitute x = 5 into the function: f(5) = (5)² - 3(5) + 2 f(5) = 25 - 15 + 2 f(5) = 10 + 2 f(5) = 12 Now, we use this result, 12, as the new input for the function, to find f(f(5)) which is f(12). Substitute x = 12 into the function: f(12) = (12)² - 3(12) + 2 f(12) = 144 - 36 + 2 f(12) = 108 + 2 f(12) = 110. Thus, f(f(5)) equals 110.

Explanation

We are given the ratio of combinations ^(2n)C₃ : ⁿC₂ = 12 : 1. Using the combination formula ᵏCᵣ = k! / (r! * (k-r)!), we expand both terms: ^(2n)C₃ = (2n)(2n-1)(2n-2) / (3 2 1) = 2n(2n-1)(n-1) / 3 ⁿC₂ = n(n-1) / (2 * 1) = n(n-1) / 2 Now, set up the ratio: [2n(2n-1)(n-1) / 3] / [n(n-1) / 2] = 12 / 1 Assuming n > 1 (required for both combinations to be defined and positive), we can cancel n(n-1) from the numerator and denominator: [2(2n-1) / 3] * 2 = 12 4(2n-1) / 3 = 12 Multiply both sides by 3: 4(2n-1) = 36 Divide both sides by 4: 2n-1 = 9 Add 1 to both sides: 2n = 10 Divide by 2: n = 5.

Explanation

Variance is a measure of how spread out a set of numbers is from its mean. If all the numbers in a dataset are identical, it means there is no spread or deviation from the mean. For the given set of numbers (7, 7, 7, 7, 7): First, calculate the mean (average) of the data. Mean = (7 + 7 + 7 + 7 + 7) / 5 = 35 / 5 = 7. Next, calculate the deviation of each data point from the mean and square it. (7 - 7)² = 0² = 0 (7 - 7)² = 0² = 0 (7 - 7)² = 0² = 0 (7 - 7)² = 0² = 0 (7 - 7)² = 0² = 0 The sum of these squared deviations is 0 + 0 + 0 + 0 + 0 = 0. Finally, the variance is the sum of squared deviations divided by the number of data points. Variance = 0 / 5 = 0. Therefore, when all data points are the same, the variance is always zero.

Explanation

To find log10(5), use the property log10(5) = log10(10/2) = log10(10) - log10(2) = 1 - 0.30103 = 0.69897. Option D is the closest approximation.

Explanation

To solve the inequality 2x + 10 >= 0, we first isolate the term with x. Subtract 10 from both sides of the inequality, which gives 2x >= -10. Next, divide both sides by 2 to solve for x. This operation yields x >= -5.

Explanation

A series is an arithmetic series if the difference between consecutive terms is constant. Let's calculate the difference between the second and first terms: 5/6 - 1/2 = 5/6 - 3/6 = 2/6 = 1/3. Now, calculate the difference between the third and second terms: 7/6 - 5/6 = 2/6 = 1/3. Since the common difference is constant (1/3), the given series is an arithmetic series.

Explanation

The area of a triangle with vertices (x1, y1), (x2, y2), and (x3, y3) can be calculated using the formula: Area = 0.5 |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|. Substituting the given coordinates (1, 6), (3, 0), and (-3, -7), we get Area = 0.5 |1(0 - (-7)) + 3(-7 - 6) + (-3)(6 - 0)|. This simplifies to 0.5 |1(7) + 3(-13) + (-3)(6)|, which is 0.5 |7 - 39 - 18|. This further simplifies to 0.5 * |-50|, resulting in an area of 25 square units.

Explanation

To find the angle between two lines, we first determine their slopes. For the first line, 3x + y - 7 = 0, the slope m1 is -3. For the second line, x + 2y + 9 = 0, the slope m2 is -1/2. The tangent of the angle theta between two lines is given by the formula tan(theta) = |(m1 - m2) / (1 + m1m2)|. Substituting the slopes, we get tan(theta) = |(-3 - (-1/2)) / (1 + (-3)(-1/2))| = |(-3 + 1/2) / (1 + 3/2)| = |(-5/2) / (5/2)| = |-1| = 1. Since tan(theta) = 1, the angle theta is 45°.

Explanation

The value of sec 60° can be found using the trigonometric identity sec² x = 1 + tan² x. Given tan 60° = sqrt(3), we substitute this into the identity: sec² 60° = 1 + (sqrt(3))² = 1 + 3 = 4. Taking the square root, sec 60° = 2, as the secant of 60° in the first quadrant is positive. Alternatively, we know that cos 60° = 1/2, and sec 60° is the reciprocal of cos 60°, so sec 60° = 1 / (1/2) = 2.

Explanation

The area of a circle is given by the formula Area = pi r², where r is the radius. We are given that the area is 154 square units. Using the approximation pi = 22/7, we can set up the equation: (22/7) r² = 154. To find r², we rearrange the equation: r² = 154 (7/22). Dividing 154 by 22 gives 7, so r² = 7 7 = 49. Taking the square root, the radius r = 7 units. The information about the diameter equations is extraneous for finding the radius.

Explanation

Cloves are a well-known spice derived from the plant Syzygium aromaticum. The characteristic aromatic part of the clove, used in cooking and traditional medicine, is actually the dried, unopened flower bud of the clove tree. These buds are harvested before they fully open and are then dried, which gives them their distinctive flavor and appearance.

Explanation

Oncogenes are genes that have the potential to cause cancer. In their normal, non-mutated form, these genes are called proto-oncogenes and play crucial roles in regulating cell growth, division, and differentiation. However, when proto-oncogenes undergo mutations or become overexpressed, they can transform into oncogenes, leading to uncontrolled cell proliferation and the development of cancerous tumors. Therefore, oncogenes are directly associated with cancer.

Explanation

The reactivity of metals is determined by their tendency to lose electrons and form positive ions. Among the given options, potassium (K) is an alkali metal found in Group 1 of the periodic table, below sodium (Na). In the reactivity series, reactivity generally increases down a group for alkali metals. Potassium is more reactive than sodium, which is more reactive than calcium (an alkaline earth metal), and all three are significantly more reactive than iron (a transition metal). Thus, potassium is the most reactive metal listed.

Explanation

Arthur Kornberg was awarded the Nobel Prize in Physiology or Medicine in 1959, along with Severo Ochoa, for their discoveries concerning the mechanism of biological synthesis of ribonucleic acid and deoxyribonucleic acid (DNA). Kornberg successfully isolated DNA polymerase and demonstrated the enzymatic synthesis of DNA in vitro, proving that DNA could be replicated outside of a living cell.

Explanation

The atomic bomb dropped on Nagasaki, Japan, on August 9, 1945, was codenamed "Fat Man" and used plutonium as its fissionable material. In contrast, the bomb dropped on Hiroshima, "Little Boy," used uranium-235. Plutonium-239 is a synthetic radioactive element produced in nuclear reactors, and its use marked a significant development in nuclear weapon technology.

Explanation

Nicolaus Copernicus was a Renaissance-era mathematician and astronomer who formulated a model of the universe that placed the Sun, rather than Earth, at the center of the universe. This heliocentric model, presented in his book "De revolutionibus orbium coelestium" (On the Revolutions of the Heavenly Spheres) published in 1543, fundamentally challenged the prevailing geocentric view and laid the foundation for modern astronomy.

Explanation

Cosmic rays are high-energy particles that originate in outer space and travel at nearly the speed of light. They are predominantly composed of charged particles, primarily protons (about 90%) and atomic nuclei (about 9%), with a smaller fraction of electrons. While there are also gamma rays (uncharged photons) associated with cosmic phenomena, the term "cosmic rays" primarily refers to these energetic charged particles.

Explanation

Carbon is the defining element of all organic compounds. Organic chemistry is essentially the study of carbon and its compounds, particularly those containing carbon-hydrogen bonds. Carbon's unique ability to form stable covalent bonds with itself and with a wide variety of other elements, forming long chains, branched structures, and rings, is responsible for the immense diversity and complexity of organic molecules essential for life.

Explanation

Ionizing radiation, such as X-rays and gamma rays, is a well-known carcinogen that can damage DNA and lead to the development of cancer over time. However, in controlled medical applications, high doses of ionizing radiation are precisely used in radiation therapy to destroy cancerous cells and shrink tumors, thereby serving as a crucial method for cancer treatment. This dual nature of causing and curing cancer makes ionizing radiation unique among the options.

Explanation

The total volume of blood in a normal adult human being is typically between 4.5 and 5.5 litres, which accounts for about 7% of an individual's body weight. This range ensures the efficient transport of oxygen, nutrients, hormones, and waste products throughout the body, as well as playing vital roles in immunity and temperature regulation. Therefore, 5-6 litres is the most accurate option provided.

Explanation

Typhoid fever and cholera are both bacterial diseases primarily transmitted through the ingestion of food or water contaminated with the feces of an infected person. Salmonella typhi causes typhoid, and Vibrio cholerae causes cholera. Due to their common mode of transmission via contaminated water sources, they are classic examples of waterborne diseases. While they are also infectious diseases, 'waterborne' provides a more specific classification based on their transmission route.

Explanation

In the human body, glucose, which is the primary source of energy, is stored in a complex carbohydrate form called glycogen. This glycogen is predominantly stored in the liver and muscle cells. Liver glycogen maintains blood glucose levels, while muscle glycogen provides readily available energy for muscle contraction during physical activity. Therefore, glycogen is the specific storage form for energy in these tissues.

Explanation

Antonie van Leeuwenhoek, a Dutch scientist, is widely recognized as the "Father of Microbiology." In 1676, using microscopes he designed himself, he was the first to observe and accurately describe single-celled organisms, which he called "animalcules." These observations included various forms of bacteria and protozoa, marking the discovery of bacteria. Alexander Fleming is known for discovering penicillin.

Explanation

Adaptation is the process by which organisms evolve to become better suited to their environment. This process, driven by natural selection, leads to the accumulation of diverse traits in populations inhabiting different ecological niches, resulting in the vast biological diversity observed on Earth. Over geological timescales, adaptations to varied conditions like climate, food sources, and predators create distinct species and contribute significantly to large-scale biodiversity.

Explanation

Vermiculture is the process of culturing or raising worms, particularly earthworms, for various purposes. These worms are often used to decompose organic food and waste materials, producing a nutrient-rich soil amendment known as vermicompost. It is an environmentally friendly method of waste management and soil improvement.

Explanation

Mycoplasmas are the smallest known free-living organisms capable of autonomous growth and reproduction. Unlike viruses, they do not require a host cell for replication. They are a genus of bacteria characterized by the absence of a cell wall, which contributes to their small size and pleomorphic (variable) shapes, and makes them resistant to many common antibiotics that target cell wall synthesis.

Explanation

The world's first successful human heart transplant was performed by Dr. Christiaan Barnard on December 3, 1967. This historic medical procedure took place at Groote Schuur Hospital in Cape Town, South Africa. The recipient, Louis Washkansky, lived for 18 days after the surgery.

Explanation

The kidneys receive a remarkably high blood flow, which is essential for their function of filtering waste products from the blood and maintaining fluid and electrolyte balance. On average, approximately 1200 cubic centimeters (or 1200 ml) of blood flows through both kidneys per minute. This represents about 20-25% of the total cardiac output at rest.

Explanation

A plant bud is an immature or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem. A bud may develop into a leaf, flower, or an entire shoot. It contains meristematic tissue, which is responsible for cell division and growth, allowing the bud to differentiate and expand into new plant parts.

Explanation

Butane is a highly flammable hydrocarbon gas that is commonly used as a fuel for lighters, portable stoves, and as a propellant in aerosol sprays. It is preferred for cigarette lighters due to its property of liquefying easily under pressure, allowing a significant amount of fuel to be stored in a small canister and vaporized for combustion when released.
