Vedclass · Answer

(D) In the phylum $Annelida$, organisms can be either unisexual or bisexual.$Nereis$ is an aquatic form which is dioecious (unisexual), meaning male and female reproductive organs are present in separate individuals.Earthworms $(Pheretima)$ and leeches $(Hirudinaria)$ are monoecious (bisexual or hermaphrodite), meaning both male and female reproductive organs are present in the same individual.Therefore, the correct classification is: Unisexual organisms $(Nereis)$ and Bisexual organisms $(Earthworm, Leech)$.
