Rickets is caused by the deficiency of `-`

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Rickets**: Rickets is a condition characterized by the softening and weakening of bones in children, primarily due to a deficiency of certain nutrients.

2. **Identifying Nutrient Deficiencies**: The question provides four options: Vitamin A, Vitamin C, Vitamin D, and Vitamin B. We need to determine which vitamin deficiency is linked to rickets.

3. **Analyzing Vitamin A**: Vitamin A is essential for vision and immune function. Its deficiency leads to issues such as night blindness and not bone-related problems. Therefore, Vitamin A is not the cause of rickets.

4. **Analyzing Vitamin C**: Vitamin C deficiency leads to scurvy, which is characterized by symptoms like bleeding gums and weakness. It does not affect bone health directly, so Vitamin C is also not the cause of rickets.

5. **Analyzing Vitamin D**: Vitamin D is crucial for the absorption of calcium and phosphorus in the body. A deficiency in Vitamin D leads to reduced absorption of these minerals, which are vital for bone health. This deficiency is directly linked to the development of rickets.

6. **Conclusion**: Based on the analysis, we conclude that rickets is caused by a deficiency of Vitamin D.

**Final Answer**: Rickets is caused by the deficiency of Vitamin D.
