Correct answer: D. Parapodia
- A. Cell wall
- B. Prostomium
- C. Nucleolus
- D. Parapodia
Explanation
The correct answer is d) Parapodia. Parapodia are fleshy, paddle-like structures that extend from the sides of the body segments in many annelids. They are specialized for locomotion, respiration, and sometimes serve as gills. Chitinous setae are present on the parapodia, and they play a crucial role in helping the annelids move through their environment by providing grip and traction.
