C) Rodents with black fur color will decrease in frequency as they are more visible to the predator against the light sand background.
Explanation:
As we know that the area that the rodents were released has a light color and a rodent predator, we can conclude that the black-colored rodents will be the ones that will be most captured by the predator and will decrease its frequency.
