San Marino, New Zealand, and Armenia are not correct for this specific Kerala context.

Satara district in Maharashtra is home to one of India's largest wind energy farms. The region's geography and wind patterns make it ideal for harnessing wind power. The other options (nuclear, hydroelectric, thermal) are not what Satara is specifically known for.

The Gandhara school of art (question says Gandharv) is known for its distinct iconography that differs from pure Greek or Roman styles despite showing Greek influence. The Indian iconographic elements make these Buddha sculptures uniquely Indian in their symbolic representation and styling.

Theodore Maiman (spelled incorrectly as 'Theodre Maimen' in the option) built the first working laser at Hughes Research Laboratories in 1960. The other names are not associated with laser invention - Denis Papin was a physicist, Francis Crick discovered DNA structure, and William Morton was a dentist.

The Dutch were the first to start a joint stock company (VOC - Dutch East India Company) to trade with India in 1602. They established trade centers before the British East India Company. The Portuguese came earlier but didn't use the joint stock model initially, and the Danish and French came later.

Article 15 of the Indian Constitution prohibits discrimination by the state against any citizen on grounds of religion, race, caste, sex, or place of birth. Article 14 is equality before law, Article 16 is equal opportunity in employment, and Article 17 abolishes untouchability.

West Bengal was the first state to enact an Anti-Defection Law in 1979, before the national constitutional amendment (52nd Amendment, 1985) that introduced the Tenth Schedule. This state law served as a precursor to the national anti-defection framework.

Aryabhatta is credited with the invention and use of zero as a number in the 5th century CE. While the concept existed in earlier civilizations, Aryabhatta formalized zero's use in mathematical calculations and the decimal system. Bhaskara, Varahamihira were later astronomers, and Archimedes was Greek.

The Dinesh Goswami Committee (1990) was indeed formed to recommend electoral reforms in India. It suggested changes like state funding of elections, disqualification of party members who defect, and amendments to the Anti-Defection Law. The other options are incorrect - the Chakmas issue relates to refugee problems, bank nationalization was addressed by different committees, and educational reforms by others.

Hydrogen is correct because its combustion produces only water vapor (H2O), making it the cleanest burning fuel among the options. Coal produces maximum pollutants including CO2, SO2, NOx, and particulate matter. Diesel and kerosene are fossil fuels that produce various emissions including carbon monoxide, unburnt hydrocarbons, and particulates. Hydrogen fuel cells produce zero emissions at point of use.

Kochi is correct. Cochin Shipyard Limited (CSL) in Kochi is the largest shipbuilding and ship repair facility in India. It has the capacity to build ships up to 1.1 lakh DWT and repair ships up to 2.5 lakh DWT. Mumbai has Mazagon Dock, Visakhapatnam has Hindustan Shipyard, and Kolkata has Garden Reach Shipbuilders, but Kochi's facility is larger in terms of capacity and infrastructure.

The sixth week is correct. The human heart begins beating around day 22-23 of embryonic development (approximately 3 weeks), but it becomes detectable and more rhythmic by the sixth week. The heart is one of the first organs to function in the embryo. The first heartbeat occurs in the third week, but by the sixth week it's clearly established and can sometimes be detected via early ultrasound.

Calcium carbonate and magnesium carbonate are correct. Pearls are primarily composed of calcium carbonate (CaCO3) in the form of aragonite crystals, held together by conchiolin (an organic protein). Natural pearls also contain small amounts of magnesium carbonate. The other options are incorrect - CO & CO2 are gases, calcium hydroxide is a different compound, and sodium oxide is not found in pearls.

Total Internal Reflection is correct. Optical fibers work on the principle of Total Internal Reflection (TIR). Light signals travel through the core (higher refractive index) and when they strike the core-cladding boundary at an angle greater than the critical angle, they are completely reflected back into the core. This allows light to travel long distances with minimal loss. Refraction would cause light to escape, scattering causes loss, and interference is not the principle.
