The correct answer is B. The percentage of the population with white fur will decrease
Explanation:
In the case presented, the fur of rabbits is related to an adaptation to survive during different seasons. In this way, the white fur is needed during winters as this helps rabbits to camouflage in an environment of snow providing them with a survival and reproduction advantage. On the other hand, the brown fur is better during summer as they need to camouflage between the brown trees, grass, and plants.
According to this, if temperature increases and therefore snow decreases the rabbits with brown fur will prevail as this will make them more likely to survive and reproduce, for example, a rabbit with white fur would be easily found by predators if there is no snow. Thus, in this case, "the percentage of the population with white fur will decrease".
