The correct answer is "populations."
Natural selection is a process whereby certain traits or characteristics become more or less common in a population over time. It occurs because individuals with certain traits are more likely to survive and reproduce in a given environment, passing on those traits to their offspring. Over many generations, this can lead to changes in the frequency of different traits within a population, which is known as evolution.
To arrive at the correct answer, you can understand how natural selection operates. It acts on individuals within a population that possess certain genotypes (the genetic makeup of an organism). These genotypes give rise to specific phenotypes (the observable traits or characteristics). Individuals with advantageous phenotypes are more likely to survive and reproduce, while those with less advantageous phenotypes are less likely to pass on their genes. This differential reproductive success can cause a change in the frequency of specific genotypes within a population over time.
So, while natural selection does act on genotypes and phenotypes of individuals, the ultimate outcome is the change in populations over generations.
