Select the correct graph.
The rock pocket mouse (Chaetodipus intermedius) is a species of rodent commonly found in the deserts of Mexico and the southwestern United States. Suppose a population of rock pocket mice lives in an area of rocky terrain. The graph below shows the distribution of body sizes within the population at the time the mice began to live among the rocks. Over time, mice with smaller bodies were better able to hide from predators than larger mice. Based on this information, which of the following graphs shows the most likely distribution of body sizes within the current population of rock pocket mice?
