Question

Match LIST-I with LIST-II

Choose the correct answer from the options given below:

• A. A-I, B-III, C - IV, D - II
• B. A - III, B - II, C - IV, D - I
• C. A-I, B-II, C - IV, D - III
• D. A-III, B - IV, C - I, D - II

Hint:

Associate keywords with each vitamin: Biotin $\rightarrow$ Coenzyme/Carboxylation, B12 $\rightarrow$ Red Blood Cells/DNA, C $\rightarrow$ Collagen/Scurvy, K $\rightarrow$ Klotting (clotting).

Answer 1

The Correct Option is D

Step 1: Concept Overview:
The question requires matching vitamins (LIST-I) with their corresponding functions in the body (LIST-II).
Step 2: Detailed Solution:
Identifying the primary function of each vitamin:


A. B7 (Biotin): Biotin acts as a coenzyme for carboxylase enzymes, vital for fatty acid synthesis, isoleucine and valine synthesis, and gluconeogenesis. Matches III. Coenzyme in synthesis of fat, glycogen and amino acids.

B. B12 (Cobalamin): B12 is crucial for DNA synthesis, red blood cell maturation, and nucleic acid production. Matches IV. Production of nucleic acids and red blood cells.

C. C (Ascorbic acid): Vitamin C is a necessary cofactor for enzymes involved in proline and lysine hydroxylation during collagen synthesis. Matches I. Used in collagen synthesis.

D. K (Phylloquinone): Vitamin K is essential for synthesizing proteins needed for blood coagulation in the liver. Matches II. Important in blood clotting.

Step 3: Final Conclusion:
The correct matches are A-III, B-IV, C-I, D-II, corresponding to option (D).
