Question

which one? annelids that have parapodia and setae polychaetes oligochaetes hirudineans

Explanation:

Polychaetes are a class of annelids characterized by having parapodia (paired appendages) and setae (bristles) for locomotion and other functions. Oligochaetes (like earthworms) have setae but lack parapodia, and hirudineans (leeches) lack both parapodia and many setae. So the annelids with parapodia and setae are polychaetes.

Answer:

A. polychaetes
