The correct option is C Parapodia
Arthropoda is the largest phylum of kingdom Animalia which includes insects. They have organ-system level of organisation. The body of arthropods is covered by chitinous exoskeleton. They have jointed appendages. Metameric segmentation is also seen in arthropods.
Most species of polychaete annelids exhibit paired, fleshy parapodia which are segmentally arranged along the body axis. Parapodia vary greatly in size and form, reflecting their variety of functions, such as gas exchange, anchorage, protection and locomotion.
