C. Nutrition
D. Protection

Answer

**Step-by-Step Solution:**

1. **Identify the Structure**: The question refers to the tapetum, which is the innermost wall layer of the anther in flowering plants.

2. **Understand the Anther's Structure**: The anther is a part of the male reproductive organ of a flower, typically bilobed and contains pollen grains. It has four wall layers:
- Epidermis
- Endothecium
- Middle layer
- Tapetum (innermost layer)

3. **Function of the Other Layers**: The outer three layers (epidermis, endothecium, and middle layer) primarily provide protection and facilitate the dehiscence (the release of pollen).

4. **Focus on the Tapetum**: The tapetum is specifically responsible for nourishing the developing pollen grains. It provides essential nutrients and support during the development of pollen.

5. **Conclusion**: The main function of the tapetum is nutrition, as it nourishes the developing pollen grains.

**Final Answer**: The main function of the tapetum is to provide nutrition to the developing pollen grains.
