Question

Match the vitamins given in Column (I) with the diseases caused by their deficiency in Column (II):
Column (I): A) Vitamin A, B) Vitamin B₁, C) Vitamin C, D) Vitamin K, E) Vitamin B₁₂.
Column (II): a) Increase in clotting time of blood, b) Night blindness, c) Beri-beri, d) Pernicious anaemia, e) Scurvy.

• A. A-(d), B-(c), C-(e), D-(a), E-(b)
• B. A-(b), B-(c), C-(e), D-(a), E-(d)
• C. A-(a), B-(b), C-(c), D-(d), E-(e)
• D. A-(b), B-(a), C-(e), D-(d), E-(c)

Hint:

Vitamin A → night blindness, B₁ → beri-beri, C → scurvy, K → clotting, B₁₂ → pernicious anaemia.

Answer 1

The Correct Option is B

Step 1: Build the correct pairings one vitamin at a time using standard biochemistry facts.
Step 2: A (Vitamin A) protects vision in dim light, so its lack gives night blindness = (b). B₁ (thiamine) supports carbohydrate metabolism, so its lack gives beri-beri = (c).
Step 3: C (ascorbic acid) maintains connective tissue, so its lack gives scurvy = (e). K aids the clotting cascade, so its lack raises blood clotting time = (a). B₁₂ (cobalamin) is essential for red-cell maturation, so its lack gives pernicious anaemia = (d).
Step 4: Collecting: A-b, B-c, C-e, D-a, E-d, which is \[ \boxed{\text{Option (ii)}} \]
