Solution

The correct option is B Variation
  • The difference between traits in individuals of the same species is known as variation.
  • Individuals have variations within their heritable traits. Some variations make an individual better suited to survive and reproduce in their environment.
  • The heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur colour. Rather, a genetic mutation causes a difference in fur colour, which may help that rabbit hide better in its environment.
So, the correct option is B.
