Answer:
Correct option - (D)
Physalia is not polymorphic.
Explanation:
Polymorphism is a phenomenon where an organism can show different forms during their lives.
Coelenterate is the organism that has two forms in their lives - polyp and medusa. But not all coelenterate show this characteristic. Porpita, Vellela, and Adamsia alternate between the medusa and polyp forms in their lifetime. Thus, they are polymorphic. Physalia belongs to Schyphozoa. It has a dominant medusa phase and no polyp phase. Since it shows only one phase, it is not polymorphic in nature.
So the correct option is (D) Physalia.
