D. duodenum

Answer

To answer the question regarding the site where complete digestion of food takes place in the alimentary canal, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Alimentary Canal**: The alimentary canal is a continuous tube that runs from the mouth to the anus, and it includes various organs such as the stomach, small intestine (which consists of the duodenum, jejunum, and ileum), and large intestine.

2. **Identifying Digestion Sites**:
- **Stomach**: The stomach is involved in the initial stages of digestion, particularly the breakdown of proteins, but it does not complete the digestion of all food types.
- **Duodenum**: This is the first part of the small intestine where some digestion occurs, especially with the help of bile and pancreatic enzymes, but it is not where digestion is completed.
- **Jejunum**: This is the middle section of the small intestine where absorption of nutrients begins, but it is not the final site of complete digestion.
- **Ileum**: This is the last part of the small intestine. It is primarily responsible for the absorption of nutrients and is where the final stages of digestion occur.

3. **Conclusion**: Based on the roles of each section of the alimentary canal, the ileum is the site where complete digestion of food takes place before the nutrients are absorbed into the bloodstream.

### Final Answer:
The site where complete digestion of food takes place in the alimentary canal is **C. ileum**.
