Options

A. Fats
B. Carbohydrate
C. Protein
D. All of these

Answer

**Step-by-Step Solution:**

1. **Identify the Function of the Stomach:**
The stomach plays a crucial role in the digestive process. It is primarily involved in the breakdown of food through mechanical and chemical means.

2. **Understand the Types of Digestion in the Stomach:**
- The stomach is known for the digestion of proteins.
- It does not significantly digest fats or carbohydrates.

3. **Recognize the Role of Enzymes:**
- The key enzyme responsible for protein digestion in the stomach is pepsin.
- Pepsin is activated in the presence of hydrochloric acid (HCl), which is secreted by the stomach lining.

4. **Explain the Process of Protein Digestion:**
- When proteins enter the stomach, pepsin breaks them down into smaller peptides called peptones and proteases.
- This process continues until the partially digested proteins move into the small intestine for further digestion.

5. **Conclusion:**
Based on the information, the stomach is the main site for the digestion of proteins, making it the correct answer.

**Final Answer:**
The stomach is the main site for the digestion of proteins.
