Quizplus · Accepted Answer

In directional selection, the environment selects for individuals that exhibit a particular trait, resulting in a shift in the population towards that trait. This means that the population is strongly selected for in one direction, such as larger beak size. Thus, option C is the correct answer. Options A, B, D, and E are not correct because they do not accurately describe what happens in directional selection.
