Quizplus · Accepted Answer

Polychaetes are segmented worms that possess chaetae (bristles) and nephridia (excretory organs). They also exhibit coordinated movements of circular and longitudinal muscle, which allows for locomotion and movement through their environment. Millipedes, tapeworms, hookworms, and flatworms all lack certain traits that are found in the polychaetes, making them less likely candidates.
