The RIGHT ANSWER IS A.
A. adaptive radiation.
Step-by-step explanation:
Adaptive radiation
It's a form of evolutionary biology. In Adaptive radiation there is a relatively fast evolution of many species from a single common ancestor I.e a specie changes rapidly from an ancestral species into a different or groups of new forms.
It mostly occurs when an organism lives a new area and different traits affect its survival. E.g development of mammals after the extinction of dinosaurs.
