Vedclass · Answer

(C) In the phylum $Annelida$,most species are hermaphroditic (monoecious),meaning both male and female reproductive organs are present in the same individual. Examples include $Pheretima$ (Earthworm) and $Hirudinaria$ (Leech).However,$Nereis$ is an aquatic annelid that is dioecious,meaning the sexes are separate (male and female individuals are distinct).$Ascaris$ is not an annelid; it belongs to the phylum $Aschelminthes$ (Nematoda).Therefore,the correct answer is $Nereis$.
