Answer 2

D. Some environmental change has happened that favors the red flowers.

Step-by-step explanation:

According to the given information, the original Phlox population had equal proportions of white, pink, and red flowers. During the study time, some changes in environmental conditions led to increase in survival and reproductive fitness of red flowers over the other two colors of the flower. Natural selection favored the red flowers which in turn led to their increase in the population.
