D. Vitamin K-Water soluble -Pellagra

Answer

To determine which option correctly matches a vitamin with its nature (fat-soluble or water-soluble) and its deficiency disease, we can analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Vitamin Types**:
- Vitamins are categorized into two main types: fat-soluble and water-soluble.
- **Fat-soluble vitamins** include Vitamin A, D, E, and K.
- **Water-soluble vitamins** include the B-complex vitamins and Vitamin C.

2. **Analyzing Each Option**:
- **Option (a)**: Vitamin A - Fat soluble - Night blindness
- Vitamin A is indeed a fat-soluble vitamin.
- Its deficiency can lead to night blindness.
- **Conclusion**: This option is correctly matched.

- **Option (b)**: Vitamin B - Fat soluble - Beri-beri
- Vitamin B is not fat-soluble; it is water-soluble.
- Beri-beri is caused by a deficiency of Vitamin B1 (Thiamine), which is a water-soluble vitamin.
- **Conclusion**: This option is incorrectly matched.

- **Option (c)**: Vitamin K - Fat soluble - Beri-beri
- Vitamin K is a fat-soluble vitamin.
- However, its deficiency does not cause beriberi; it can lead to bleeding disorders due to impaired blood clotting.
- **Conclusion**: This option is incorrectly matched.

- **Option (d)**: Vitamin K - Water soluble - Pellagra
- Vitamin K is fat-soluble, not water-soluble.
- Pellagra is caused by a deficiency of Vitamin B3 (Niacin), not Vitamin K.
- **Conclusion**: This option is incorrectly matched.

3. **Final Conclusion**:
- The only correct match is **Option (a)**: Vitamin A - Fat soluble - Night blindness.

### Summary:
The correct answer is **(a) Vitamin A - Fat soluble - Night blindness**.
