B.planarians

C.roundworms

D.flukes

E.All worms are segmented

Solution

Choice A iscorrect.

Reason: Phylum annelida represents worms with segmented body. They also have radial symmetry and small segments can be found on their body. These segments are true segments in nature which means that external segment corresponds to internal segmentation. Further, the ventral parts of these segments also contain pseudopodia in some annelids. Thus, annelids represent true segmented bodies such as in earthworm.
