Approach Solution -2
Excretory structures in nematodes are associated with a ventral excretory pore rather than caudal sensory structures, and general body movement is governed by muscle bands, not sensory organs, so both can be ruled out. 'Secretion' is too generic a label for a structure that is specifically described as sexually dimorphic. A caudal organ that differs in form between males and females points to a role in locating and recognising a mate during copulation, which places its function under reproduction.
