Answer:
The correct answer is "A fish population in which the average skin brightness decreases over several generations in the presence of predators"
Explanation:
In biology, an adaptation is defined as an evolutionary response at which a group of organism develop new traits or behaviors as result of new environmental conditions. In this case, a fish population which skin brightness decreases over several generations in the presence of predators is an example of an adaptation. The fish decreasing its bright skin is the new trait developed as a result of the presence of predators, and as stated, adaptation occurs over several generations not within one generation.
