Options

A. stomach
B. jejunum
C. ileum
D. caecum

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where amino acids are absorbed in the digestive system.

2. **Identifying the Options**: The options provided are:
- Stomach
- Jejunum
- Ileum
- Cecum

3. **Analyzing Each Option**:
- **Stomach**: The stomach primarily functions in the digestion of proteins through the action of gastric juices but does not absorb amino acids.
- **Jejunum**: The jejunum is a part of the small intestine and is primarily responsible for the absorption of nutrients, including amino acids.
- **Ileum**: The ileum is the last part of the small intestine and does absorb some nutrients, but its main role is in the absorption of bile acids and vitamin B12.
- **Cecum**: The cecum is part of the large intestine and mainly absorbs fluids and salts, not amino acids.

4. **Conclusion**: Based on the analysis, the jejunum is the primary site for the absorption of amino acids in the digestive system.

5. **Final Answer**: Amino acids are absorbed by the **jejunum**.
