Explanation:
Evolution refers to the gradual development of living organisms from earlier forms to the forms that exist today. One of the principal factors that lead to evolution is the ability of an organism to adapt to adverse changes in its environment. Organisms that are able to survive adverse changes in their environments usually go on to produce offspring that possess their parents' ability to survive. A good example of this is given in option C, where individuals with denser fur were able to survive from severe cold and then give birth to young ones that inherit their parents' ability to survive severe cold.
