Which one is the correct match ?

Options

A. Calcium - beri - beri
B. Na - Addison's disease
C. Iron - haemophilia
D. P - bone fragility.

Answer

To solve the question of which one is the correct match between minerals and their associated deficiency diseases, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Option A: Calcium and Beriberi**
- Calcium is essential for bone health and its deficiency can lead to bone deformities. However, beriberi is a disease caused by a deficiency of Vitamin B1 (thiamine), not calcium.
- **Conclusion**: This option is incorrect.

2. **Option B: Sodium and Addison's Disease**
- Sodium is important for nerve function and its deficiency can lead to conditions like hyponatremia. Addison's disease, however, is related to adrenal insufficiency and is not directly caused by sodium deficiency.
- **Conclusion**: This option is also incorrect.

3. **Option C: Iron and Hemophilia**
- Iron deficiency leads to anemia, characterized by low hemoglobin levels. Hemophilia, on the other hand, is a genetic disorder that affects blood clotting due to the absence of certain clotting factors. It is not caused by iron deficiency.
- **Conclusion**: This option is incorrect.

4. **Option D: Phosphorus and Bone Fragility**
- Phosphorus, along with calcium, is crucial for bone formation. A deficiency in phosphorus can lead to fragile bones, making them more susceptible to fractures.
- **Conclusion**: This option is correct.

### Final Answer:
The correct match is **Option D: Phosphorus and Bone Fragility**.
