The ciliated comb plates in pleurobrachia are meant for

Options

A. Reproduction
B. Digestion
C. Protection
D. Locomotion

Explanation

**Step-by-Step Solution:**

1. **Identify the Organism**: The question refers to "pleurobrachia," which belongs to the phylum Tenophora.

2. **Understand the Structure**: Pleurobrachia has ciliated comb plates. These are rows of cilia that are fused at their base to form a structure known as comb plates.

3. **Function of Cilia**: The cilia on the comb plates beat in a coordinated manner. This movement is crucial for the organism's ability to move through the water.

4. **Determine the Purpose**: The primary function of these ciliated comb plates is locomotion. They help the pleurobrachia to swim and navigate through its aquatic environment.

5. **Eliminate Other Options**: The other options provided (reproduction, digestion, protection) do not relate to the function of the ciliated comb plates. They are specifically adapted for movement.

6. **Conclusion**: Therefore, the ciliated comb plates in pleurobrachia are meant for locomotion.

**Final Answer**: The ciliated comb plates in pleurobrachia are meant for locomotion.
