A) In smoggy areas, dark moths have a higher survival rate than white moths.

Explanation:

In the forest with many trees with a light colored trunk lived moths with light colored wings. There were still a few moths with dark colored wings. The darker moths were more easily seen by birds that fed on moths. caused by the frequent use of coal to heat the houses, the tree trunks ended up with a dark color which provided the dark-winged moths with a higher survival rate. This is because they were able to camouflage themselves in the tree trunks and not be seen by predators.
