Which one of the following is the correct matching of a vitamin, its nature and its deficiency?

Options

A. Vitamin-A - Fat Soluble, night blindness
B. Vitamin-K - Fat Soluble, Beri-beri
C. Vitamin-A - Fat Soluble, Beri-beri
D. Vitamin-F - Water soluble, Pellagra

Answer

To determine the correct matching of a vitamin, its nature, and its deficiency, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Types of Vitamins**:
- Vitamins are classified into two categories: water-soluble and fat-soluble.
- Water-soluble vitamins include Vitamin B and Vitamin C.
- Fat-soluble vitamins include Vitamins A, D, E, and K.

2. **List the Deficiencies**:
- Each vitamin has a specific deficiency associated with it:
- Vitamin A deficiency leads to night blindness.
- Vitamin B1 (Thiamine) deficiency leads to beriberi.
- Vitamin B3 (Niacin) deficiency leads to pellagra.
- Vitamin K deficiency can lead to issues with blood clotting.

3. **Analyze Each Option**:
- **Option A**: Vitamin A (fat-soluble) - Night blindness (correct).
- **Option B**: Vitamin K (fat-soluble) - Beriberi (incorrect, beriberi is due to Vitamin B).
- **Option C**: Vitamin B (water-soluble) - Night blindness (incorrect, night blindness is due to Vitamin A).
- **Option D**: Vitamin F (not a standard vitamin classification) - Pellagra (incorrect, pellagra is due to Vitamin B3).

4. **Elimination Method**:
- From the analysis, we can eliminate Options B, C, and D as they do not correctly match the vitamin with its nature and deficiency.
- This leaves us with Option A as the only correct match.

5. **Conclusion**:
- The correct matching is Vitamin A (fat-soluble) and its deficiency, which is night blindness.

### Final Answer:
The correct matching of a vitamin, its nature, and its deficiency is **Vitamin A (fat-soluble) - Night blindness**.
