- B. Hydrostatic skeleton
- C. Parapodia
- D. Bones
Explanation
The locomotory organs in annelids include parapodia, suckers, and setae. Annelids are segmented worms that belong to the phylum Annelida. Their movement depends on special structures that help them crawl, burrow, or swim. According to the textbook, the organs of locomotion in annelids include parapodia, suckers, and setae. Parapodia are paired, fleshy, paddle-like structures found mainly in marine annelids such as polychaetes. They assist in crawling on the sea floor and also help in swimming. Each parapodium often contains many bristles called setae, which provide grip and support during movement. For annelids that do not have parapodia, such as earthworms, setae alone help them anchor different segments to the ground while their muscles push the body forward.
