Answer:
Correct Answer: A
Solution:
The presence of different type of individuals in a colony to perform specific functions is referred to as polymorphism. Physalia is a disc-like hydrozoid. Its colony consists of gastrozooids, dactylozooids, gonophores and gelatinous zooids. Hydra lack medusa and its polyp is solitary. Planaria is Platyhelminthes and not coelenterate.
