Solution
The correct option is B Metagenesis
Obelia shows alternation of asexual and sexual phases during its life cycle. The asexual phase is represented by the polyp while the sexual phase is medusa. The two alternate in the life cycle. Such an alternation between asexual and sexual phases is called metagenesis.
Metamerism is exhibited by animals belonging to the phylum Annelida. It is segmentation where there is a linear repetition of organs.
Regeneration is the process where a whole new organ or organism arises from a part of the parent body.
