• C. Adaptation to a particular habitat
• D. All of these

Answer 1

The correct option is A Different forms suited to inhabit different environments

Adaptive radiation is a process of evolution of an animal or plant group into a wide variety of types adapted to specialised modes of life. Darwin's finches represent the best example of adaptive radiation. About 14 species of these birds of the Galápagos Islands evolved from a single species of ground-dwelling, seed-eating finch that probably emigrated from the South American mainland.
