Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the cause of bow-shaped legs in children, specifically which vitamin deficiency is responsible for this condition.

2. **Identifying the Condition**: Bow-shaped legs in children are commonly associated with a condition known as rickets. Rickets is characterized by the softening and weakening of bones in children, often leading to deformities such as bowed legs.

3. **Linking Rickets to Vitamin Deficiency**: Rickets is primarily caused by a deficiency of vitamin D. Vitamin D is essential for calcium absorption in the body, which is crucial for maintaining healthy bones. Without adequate vitamin D, bones can become soft and lead to deformities.

4. **Eliminating Other Options**:
- Vitamin A deficiency does not cause bow-shaped legs; it primarily affects vision and immune function.
- Vitamin B deficiency can lead to various health issues but is not linked to bone deformities.
- Vitamin C deficiency leads to scurvy, which affects connective tissues but does not cause bow legs.

5. **Conclusion**: Therefore, the correct answer to the question is that bow-shaped legs in children are due to a deficiency of vitamin D.

**Final Answer**: Bow-shaped legs in children are due to a deficiency of vitamin D.
