Vedclass · Answer

(D) The incorrect match is option $(D)$.$1$. Millipede belongs to the class Diplopoda (Phylum Arthropoda). They are terrestrial and possess two pairs of jointed appendages on each body segment,respiring through tracheae. This is a correct match.$2$. Nereis belongs to the class Polychaeta (Phylum Annelida). They possess numerous setae on lateral appendages called parapodia,which help in swimming. This is a correct match.$3$. Taenia solium (Tapeworm) belongs to the class Cestoda (Phylum Platyhelminthes). Their body is covered with a thick cuticle,and they lack an alimentary canal as they absorb nutrients directly from the host's intestine. This is a correct match.$4$. Ctenophores (Phylum Ctenophora) are radially symmetrical and lack cnidoblasts (which are characteristic of Cnidaria). Crucially,they do not have a polyp stage in their life cycle. Therefore,the statement that a polyp stage is present is incorrect.
