The answer is B) whether the mutation makes some lizards more fit for their environment than other lizards.

If a mutation introduces a new skin color in a lizard population and that mutation makes some lizards more fit for their environment than other lizards then the frequency of the new allele will increase. For example, if a mutation causes some dark skin color which can help some lizards to survive. The more lizards with dark skin color will survive, and after some time, the frequency of the new allele will increase.
