- Osteomalacia is a medical condition characterized by the softening of bones. This condition is primarily due to a deficiency in certain nutrients that are crucial for bone health.

2. **Identifying the Cause**:
- The softening of bones in osteomalacia is linked to impaired bone metabolism. This impaired metabolism is often a result of insufficient levels of calcium and vitamin D in the body.

3. **Evaluating Vitamin Deficiencies**:

- **Option A: Vitamin A** - Deficiency in vitamin A is associated with night blindness, not osteomalacia.
- **Option B: Vitamin B** - Vitamin B complex consists of several vitamins, none of which are directly linked to osteomalacia.
- **Option C: Vitamin C** - A deficiency in vitamin C leads to scurvy, which is characterized by symptoms like bleeding gums, not osteomalacia.
- **Option D: Vitamin D** - Vitamin D is essential for calcium absorption and bone health. A deficiency in vitamin D directly leads to osteomalacia.

4. **Conclusion**:
- Based on the analysis, the correct answer is that osteomalacia occurs due to the deficiency of **Vitamin D**.

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