Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

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

Hint:

Vitamin Matches:
Vitamin A = Cell differentiation
Vitamin C = Bleeding gums (Scurvy)
Niacin = 4-D disease (Pellagra)
Vitamin D = Derived from 7-dehydrocholesterol.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Biochemical functions, deficiency pathology, and metabolic precursors of essential vitamins.

Step 2: Detailed Explanation:
Matching vitamins in List I with biochemical functions/diseases in List II:
- A. Vitamin A (Retinoic Acid): Crucial nuclear receptor ligand governing epithelial IV. Cell differentiation and morphogenesis.
- B. Vitamin C (Ascorbic Acid): Required for proline hydroxylase in collagen synthesis; deficiency causes Scurvy characterized by II. Bleeding gums and capillary fragility.
- C. Niacin (Vitamin B3): Deficiency causes Pellagra, known clinically as the I. 4-D disease (Dermatitis, Diarrhea, Dementia, Death).
- D. Vitamin D (Cholecalciferol): Sterol vitamin synthesized photochemically in skin from precursor III. Cholesterol (specifically 7-dehydrocholesterol).
Matching sequence: A-IV, B-II, C-I, D-III.

Step 3: Final Answer:
Hence, the correct matching is A-IV, B-II, C-I, D-III, matching option (D).
