A)
There are three variants of moths- white winged moth and dark winged moth or melanised moth. White winged moths occurred in the pollution free areas while melanised moths appeared in industrial areas. Both these coloration provided camouflage in the respective areas. 

If the industries were removed then the white winged ones would be more in number as they would get camouflaged with lichens while the melanised forms would be easily identified by the predator and hence their numbers would come down.
