D. Taenia

Answer

To solve the question "Which of the following takes food but has no alimentary canal?" we will analyze the options provided: leach, levofluke, ascaris, and taenia.

### Step-by-Step Solution:

1. **Understanding the Question**:
- The question is asking for an organism that consumes food but lacks an alimentary canal (a digestive tract).

2. **Analyzing the Options**:
- **Leach**: Leeches are annelids that have a complete digestive system, including an alimentary canal. Therefore, they do not fit the criteria.
- **Levofluke**: This is likely referring to liver flukes (e.g., Fasciola hepatica), which also possess a digestive system and an alimentary canal. Thus, they do not meet the requirement.
- **Ascaris**: Ascaris is a roundworm that has a complete digestive system with an alimentary canal. This option can be eliminated.
- **Taenia**: Taenia, specifically Taenia solium (pork tapeworm), is a flatworm that does not have an alimentary canal. Instead, it absorbs nutrients directly from the host's intestine through its body surface.

3. **Conclusion**:
- Based on the analysis, the organism that takes in food but lacks an alimentary canal is **Taenia**.

### Final Answer:
The correct option is **Taenia**.
