Among the following which disease is not caused by deficiency of vitamin D

Options

A. Rickets
B. Ostemalacia
C. Pigeon breast
D. Spure

Answer

To determine which disease is not caused by a deficiency of vitamin D, we can analyze the options provided:

1. **Rickets**: This is a disease that occurs in children due to a deficiency of vitamin D, calcium, or phosphate. It leads to softening and weakening of bones, resulting in deformities.

2. **Osteomalacia**: This condition is similar to rickets but occurs in adults. It is also caused by a deficiency of vitamin D, leading to softening of the bones.

3. **Pigeon breast (pectus carinatum)**: This is a deformity of the chest wall where the breastbone protrudes outward. While it can be associated with various conditions, it is not directly caused by vitamin D deficiency.

4. **Spurae**: This term seems to refer to a condition that is not widely recognized in medical literature. However, based on the context, it appears to be a misinterpretation or misspelling of "scurvy," which is caused by a deficiency of vitamin C, not vitamin D. Scurvy is characterized by symptoms such as ulceration of the mouth, inflammation of the bowel, and diarrhea.

Based on this analysis, the disease that is not caused by a deficiency of vitamin D is **spurae (or scurvy)**.

### Final Answer:
**Spurae (or scurvy)** is not caused by a deficiency of vitamin D.
