Solution

The correct option is D Industrial melanism in Peppered Moths
One of the most important examples of natural selection is adaptation of the colour changing behaviour of Peppered Moth Biston betularia, which is found in all parts of England. Industrial melanism is an adaptation where the moths living in the industrial areas developed melanin pigment to hide themselves from predators.
