Vedclass · Answer

(A) Phylum $Annelida$ and $Mollusca$ are both classified under the group $Lophotrochozoa$ (or $Protostomia$).Both phyla exhibit $spiral$ $cleavage$ during early embryonic development.Furthermore,in both groups,the $mesoderm$ is derived from a specific cell called the $4d$ cell (or $mesentoblast$),which is a characteristic feature of $spiral$ $cleavage$ in protostomes.Therefore,they share similarities in their early embryonic development patterns.
