On Plato the answer is (D)
Polychaetes have parapodia with chaetae for locomotion, have well-developed heads with sensory organs, exhibit a wider range of body forms, and primarily live in marine environments. Oligochaetes, on the other hand, lack parapodia and have fewer chaetae, have less specialized heads, mostly have a uniform body structure, and are mostly found in freshwater or terrestrial habitats.
Parapodia in polychaetes serve as both respiratory structures and locomotory appendages. They increase surface area for gas exchange and help in swimming, crawling, and digging through the substrate, facilitating the active lifestyle of polychaetes.
