What occurs during periods of adaptive radiation?

a.) many species become extinct.
b.) populations migrate.
c.) species evolve rapidly.
d.) geographical ranges increase.

The correct answer is option C, species evolve rapidly

Reason -

In adaptive radiation, the ancestral species diversifies at a fast rate and results into new species which have resulted due to changing climatic and environmental conditions. For example the mammals, reptiles, birds etc. all evolved from the dinosaurs after their extinction. The major impacts of adaptive radiation can be visualized when an organism moves to a new area and therefore transforms to survive.

i believe it would be c: tons.
