Chitons, snails, clams, and squid all belong to the phylum Mollusca, which is characterized by a soft, unsegmented body often protected by a hard shell. The other options given (Bivalvia, Gastropoda, and Cephalopoda) are all subclasses or orders within the phylum Mollusca. Platyhelminthes is a completely different phylum that includes flatworms, which are not closely related to mollusks.
