Solution

The correct option is D Accumulation of variations over several generations
Accumulation of variations over several generations is one of the major factors responsible for speciation. There are several other forces also acting but most important is the accumulation of variations for several generations. This ensures that variations are in accordance with the environmental conditions throughout.

Q. Assertion :As favourable variations are transmitted from generation to generation, successive generations become better adapted to the environment, more over, new adaptations may arise due to changing environment. In this way, the adaptive traits preserved by natural selection, will gradually change the characteristics of a species. Reason: This explains the origin of species.
