- **Vitamin E**: Known for its antioxidant properties, a deficiency can lead to hemolytic anemia, but it does not prevent xerophthalmia.
- **Vitamin D**: Essential for calcium metabolism and bone health. Its deficiency causes rickets, not xerophthalmia.
- **Vitamin A**: Also known as retinol, this vitamin is crucial for the synthesis of retinal pigments and is essential for normal vision. A deficiency in vitamin A leads to xerophthalmia.

4. **Conclusion**: Based on the analysis, the vitamin that prevents xerophthalmia is Vitamin A. Therefore, the correct answer is **A**.
