Solution

The correct option is B Metagenesis
Metagenesis is an alternation of sexual and asexual stages. The colonial marine hydrozoan Obelia exhibits metagenesis wherein asexual reproduction in polyp through budding produce free-swimming medusa that in turn reproduce sexually by gametic fusion. The zygote develops into planula larva which in turn develops into a polyp followed by colony formation. Neoteny refers to retention of larval features in adults while metamorphosis is the transition of developmental stages; from larva to adult. The correct answer is B.
