Solution (c)

Explanation:

• Sariska Tiger Reserve is known for the successful relocation of tigers, making it the first reserve worldwide to have relocated tigers now residing successfully. (Option (a) is correct)
• In the range of North Aravali Leopard and Wildlife Corridor, this is one of the most valuable biodiversity areas. Being part of the Khathiar-Gir forests and Aravali Range, Sariska features the best ecosystem for sheltering wildlife in the park. (Option (b) is correct)
• The Supreme Court of India clarified that protected areas include not only national parks and wildlife sanctuaries but also critical tiger habitats, including tiger reserves. Therefore, Sariska Tiger Reserve is indeed part of the protected areas. (Option (c) is incorrect)
• The main tree species in Sariska Tiger Reserve is Anogeissus pendula, commonly known as Dhok. (Option (d) is correct)

Solution (a)

Explanation:

• As of 2023, India ranks fourth globally in renewable energy capacity with 176 gigawatts installed. (Option (a) is correct)
• India is the third-largest producer of solar power, not the second. It generated 113 billion units (BU) of solar power, placing it behind China and the United States. (Option (b) is incorrect)
• While India’s renewable energy production has significantly increased, the doubling of production occurred over a longer period from 2012 to 2023. (Option (c) is incorrect)
• India has defined Green Hydrogen and has initiated processes under the National Green Hydrogen Mission to set up 4.5 lakh tonnes of Green Hydrogen Production Facilities. (Option (d) is incorrect)

Solution (c)

Explanation:

• Laboratory chemicals include inorganic chemicals, which are compounds not primarily made up of carbon atoms. Sodium chloride (NaCl) used in various laboratory experiments. (Statement 1 is correct)
• Laboratory chemicals also include organic chemicals, which are primarily composed of carbon atoms. Ethanol (C2H5OH) commonly used as a solvent in laboratory experiments. (Statement 2 is correct)
• Laboratory chemicals can be chemically defined, meaning their chemical composition is known and specified. Pure water (H2O) with known chemical composition used in various analytical procedures. (Statement 3 is correct)
• The Customs Department defines laboratory chemicals as “all chemicals, organic or inorganic, whether or not chemically defined, imported in packings not exceeding 500 gms or 500 millilitres and which can be identified with reference to the purity, markings or other features to show them to be meant for use solely as laboratory chemicals.”

Solution (d)

Explanation:

• In DNA, each deoxyribose sugar is attached to one of the four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G). In a DNA molecule, a deoxyribose unit bonded to adenine is part of the structure forming the genetic code. (Statement 1 is correct)
• The backbone of the DNA molecule is composed of alternating sugar (deoxyribose) and phosphate groups. The structure of DNA includes a sugar-phosphate backbone, where deoxyribose sugars are linked together by phosphate groups. (Statement 2 is correct)
• Deoxyribose units in the DNA backbone are connected by phosphate groups forming phosphodiester bonds. The linkage between the 3′ carbon atom of one deoxyribose sugar and the 5′ carbon atom of the next sugar in the DNA chain is made by a phosphate group. (Statement 3 is correct)
