Answer 1

Answer:

The correct answer is - option B. laws that improve air quality and restrict pollution.

Explanation:

The dark peppered moths were the adaption of the light peppered moths due to the change in the environmental condition of increased pollution that made tree bark dark in color and allows birds to easily prey on the light peppered moths.

This leads to natural selection and light moths become dark but the after Clean Air Act was that there was less pollution then there is less soot in the air, so trees were less black which result in the Light-colored moths would increase, and dark-colored moths would decrease.
