Question

The correct order of match between column X and Column Y is :

X		Y
I.	Vitamin A	i.	Muscular weakness
II.	Vitamin D	ii.	Increased blood clotting time
III.	Vitamin E	iii.	Night-blindness
IV.	Vitamin K	iv.	Osteomalacia

• A. I-iv, II-iii, III-ii, IV-i
• B. I-ii, II-i, III-iii, IV-iv
• C. I-iii, II-ii, III-iv, IV-i
• D. I-iii, II-iv, III-i, IV-ii

Answer 1

The Correct Option is D

Explanation:

Vitamin A deficiency causes Night-blindness (iii).

Vitamin D deficiency leads to Osteomalacia (iv).

Vitamin E deficiency results in Muscular weakness (i).

Vitamin K deficiency causes Increased blood clotting time (ii).

Correct matching:

Vitamin A → Night-blindness (iii)

Vitamin D → Osteomalacia (iv)

Vitamin E → Muscular weakness (i)

Vitamin K → Increased blood clotting time (ii)

Conclusion:

The correct answer is Option B: I - iii, II - iv, III - i, IV - ii.

Answer 2

Let's analyze the relationship between Vitamin X and the corresponding symptoms or deficiencies:

1. Vitamin A: Vitamin A deficiency leads to Night-blindness (iii).
2. Vitamin D: A deficiency of Vitamin D causes Osteomalacia (iv), which is characterized by softening of the bones.
3. Vitamin E: A deficiency of Vitamin E can lead to Muscular weakness (i), as it is involved in muscle function.
4. Vitamin K: Vitamin K is essential for blood clotting. A deficiency results in Increased blood clotting time (ii).

Thus, the correct matching is:
- I – iii: Vitamin A causes Night-blindness.
- II – iv: Vitamin D causes Osteomalacia.
- III – i: Vitamin E causes Muscular weakness.
- IV – ii: Vitamin K causes Increased blood clotting time.

The correct answer is: \({\text{(D) I – iii, II – iv, III – i, IV – ii}}\)
