Solution

The correct option is A Parapodia

  • Nereis is an example of the phylum Annelida. It is a genus of polychaete worms (segmented worms). It comprises many species, most of which are marine. They possess parapodia.
  • Parapodia are paired, unjointed lateral appendages found in polychaete worms, which are often fleshy (especially in marine polychaetes) and used for locomotion, respiration, and other functions.
So, the correct answer is option A.
