The correct option is D Protective camouflage with the surroundings
Industrial melanism in the case of the peppered moth Biston betularia, is a typical example of a situation wherein natural selection happens due to man - made influences. The industrial revolution in England resulted in various surfaces being covered with black soot. Species relying on camouflage as a means of avoiding predation had to adapt or risk extinction. Thus, among the two varieties of the peppered moth, the black ones turned out to be more favoured over their white counterparts as the black moths could easily remain unnoticed against the black soot - covered backgrounds.
