Answer:
the third one
Explanation:
The definition for natural selection is "the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution. Compare with survival of the fittest (see survival)."
The third question shows us natural selection. Because the population of black mice went up and the tan mice went down. this is an example of natural selection because the black mice have adapted to their environment and reproduced while the tan mice have not.
