• D. Both assertion and reason are correct

Answer 1

The correct option is B Only assertion is correct

Evolution is a slow and continuous process that takes a very long time to form a new species. Variations in species are caused not only by mutations but, can also arise due to natural selection. Mutation is the random change in an organism's genetic makeup which influences the population. Organisms that are better adapted to their environment tend to survive longer and transmit more of their genetic characteristics to succeeding generations than do those that are less well adapted, and this process is called natural selection.
