Vedclass · Answer

(C) The provided cross-section shows an outer body wall (ectoderm),a middle layer (mesoderm),and an inner gut tube (endoderm) with a fluid-filled cavity between the body wall and the gut. This indicates a pseudocoelomate body plan,where the body cavity is not lined by mesoderm on all sides.$1$. $Fasciola$ (Liver fluke) is an acoelomate (Platyhelminthes).$2$. $Pleurobrachia$ (Ctenophora) is an acoelomate.$3$. $Ascaris$ (Roundworm) belongs to the phylum Aschelminthes (Nematoda),which are characteristically pseudocoelomate.$4$. $Nereis$ (Annelida) is a true coelomate.Therefore,the correct answer is $Ascaris$.
