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.
