Explanation
The phylum Platyhelminthes consists of flatworms, which are named for their flat, dorsoventrally flattened bodies. This sets them apart from other worm-like organisms, such as roundworms (Nematoda), which have a cylindrical shape. Flatworms are simple, unsegmented invertebrates with bilateral symmetry. Other options like hookworms, threadworms, and pinworms are all roundworms and do not belong to the Platyhelminthes phylum.
