C. Blood meal
D. Digested food

Answer

**Step-by-Step Solution:**

1. **Understanding the Whipworm**: The whipworm, scientifically known as Trichuris trichiura, is a parasitic worm that primarily resides in the large intestine of its host, usually humans.

2. **Feeding Mechanism**: Whipworms do not consume food in the traditional sense. Instead, they feed on the secretions from the tissues of their host.

3. **Nature of the Secretions**: The secretions that whipworms feed on are primarily composed of digested food materials. These materials are the result of the host's digestive processes.

4. **Elimination of Other Options**:
- **A. Semi-digested food**: Whipworms do not feed on semi-digested food directly.
- **B. Undigested food**: They cannot feed on undigested food as they rely on the nutrients that have already been processed.
- **C. Blood meal**: Whipworms do not consume blood; they specifically feed on tissue secretions.

5. **Conclusion**: Based on the feeding habits of whipworms and the nature of the materials they consume, the correct answer is that whipworms feed on digested food.

**Final Answer**: D. That is a digested food.
