Vedclass · Answer

(B) The phylum $Platyhelminthes$ (flatworms) is divided into several classes based on their morphological characteristics.In the class $Cestoda$ (tapeworms),the digestive system (gut) is completely absent.These organisms live as endoparasites in the intestine of their hosts and absorb pre-digested nutrients directly through their body surface (tegument).In contrast,classes like $Turbellaria$,$Digenoidea$ (a subclass of $Trematoda$),and $Aspidogastrea$ possess a digestive tract,although it may be incomplete in some cases.

The gut is present in all of the following taxonomic groups of Platyhelminthes,except for one. Identify the group in which it is absent.
