Which one of the following pairs about organ/part that helps in locomotion is not correctly matched?

The pair Nereis: Pseudopodia is incorrectly matched. Nereis is an annelid that uses lateral appendages called parapodia for locomotion, whereas pseudopodia (false feet) are temporary protoplasmic extensions used by protozoans like Amoeba [1]. Euglena belongs to the class Mastigophora and utilizes a thread-like flagellum for movement [2]. Paramecium, a member of the class Ciliophora, is covered in numerous tiny hair-like structures called cilia that facilitate ciliary locomotion [2]. Starfish (Echinoderms) utilize a water vascular system connected to tube feet for movement and attachment. While pseudopodia are characteristic of the sub-phylum Sarcodina (e.g., Amoeba), they are not found in Nereis. Therefore, option 3 is the only incorrect pairing among the choices provided.
