Solution
The correct option is B Medusae
The genus Obelia is a marine and freshwater animal species belonging to the class Hydrazoa of the phylum Cnidaria. It shows alternation of polypoid and medusoid generations. The asexual polypoid generation gives rise to polyps and blastostyles by the process of budding. This blastostyle later forms the medusae by budding that forms gametes which fuse to form a colony of polypoid. Thus the correct answer is option B.
