Osteomalacia occurs due to the deficiency of:

Options

A. Vitamin A
B. Vitamin B
C. Vitamin C
D. Vitamin D

Answer

**Step-by-Step Solution:**

1. **Understanding Osteomalacia**: Osteomalacia is a condition characterized by the softening of bones, which can lead to pain and muscle weakness. It is important to identify the nutrient deficiency that causes this condition.

2. **Evaluating the Options**:
- **Vitamin A**: This vitamin is primarily associated with vision and its deficiency can lead to night blindness. Therefore, it is not related to osteomalacia.
- **Vitamin B**: This group of vitamins is linked to various metabolic processes. A deficiency in Vitamin B can lead to conditions like beriberi, but not osteomalacia.
- **Vitamin C**: This vitamin is vital for collagen synthesis and its deficiency leads to scurvy, which affects connective tissues but does not cause osteomalacia.
- **Vitamin D**: This vitamin is crucial for calcium absorption and bone health. A deficiency in Vitamin D leads to osteomalacia, as it impairs bone mineralization, resulting in soft bones.

3. **Conclusion**: Based on the evaluation of the options, osteomalacia occurs due to a deficiency of Vitamin D.

**Final Answer**: Osteomalacia occurs due to the deficiency of Vitamin D.
