A metozoan covered by cilia is

Options

A. paramecium
B. Dugesia
C. fasciola
D. Ascaris

Answer

To solve the question "A metazoan covered by cilia is?", we need to analyze the options provided:

1. **Paramecium**: This organism is a protozoan, not a metazoan. Therefore, we can rule this option out.

2. **Dugesia**: This is commonly known as planaria, which is a free-living flatworm belonging to the phylum Platyhelminthes. Planaria are covered with cilia, which they use for locomotion. Since it is a metazoan and covered by cilia, this option is a strong candidate.

3. **Fasciola**: This organism is a liver fluke, which is a parasitic flatworm. Parasitic flatworms do not have cilia covering their bodies, so we can eliminate this option as well.

4. **Ascaris**: This is a roundworm that belongs to the phylum Ascaris. It is also a parasitic organism and does not have cilia on its body. Thus, this option can also be ruled out.

Based on the analysis of the options, the correct answer is **Dugesia**, which is a metazoan covered by cilia.

### Final Answer:
**Dugesia (Planaria)**
