Options

A. Lemna
B. Arceuthobium
C. Spirodella
D. Wolffia

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for the smallest angiospermic (flowering) dicot parasite.

2. **List the Options**: The options provided are:
- A) Lamna
- B) Arceuthobium
- C) Spirodella
- D) Wolfia

3. **Analyze Each Option**:
- **Lamna**: This is a genus of free-floating aquatic plants and is not a parasite.
- **Arceuthobium**: This is a genus of parasitic plants that grow on pine trees. It is known to be very small, typically measuring about 5 to 8 mm in length.
- **Spirodella**: Similar to Lamna, this is also a free-floating aquatic plant and not a parasite.
- **Wolfia**: While Wolfia is one of the smallest angiosperms, it is not a parasitic plant; it is free-living.

4. **Determine the Correct Answer**: Based on the analysis, Arceuthobium is the only option that is both a dicot and a parasite, making it the smallest angiospermic dicot parasite.

5. **Conclusion**: Therefore, the answer to the question is **Arceuthobium**.
