Vedclass · Answer

(B) In $Aschelminthes$ (roundworms),the alimentary canal is complete with a well-developed muscular pharynx.Digestion is extracellular.Fertilization is internal,and development may be direct (the young ones resemble the adults) or indirect.Option $A$ is incorrect because development is not always indirect.Option $B$ is correct as they possess a complete alimentary canal and exhibit extracellular digestion.Option $C$ is partially true but $B$ is a more fundamental characteristic defined in the $NCERT$.Option $D$ is incorrect because excretion in $Aschelminthes$ occurs through an excretory pore,not nephridia (which are found in $Annelida$).
