Answer: c. The dark colored moths will experience disruptive selection.
Explanation:
The tree bark is light in color which means that while the light colored moths will be able to blend in, the dark colored moths will not. This will lead to the dark colored moths being hunted more by the bird leading to a sharp decrease in their numbers.
Disruptive selection occurs when an extreme trait is preferred over an intermediate one with little advantage in that environment. The dark moths will experience disruptive selection because the light moths are preferred for survival.
