Industrialisation and domestic coal fires had caused sooty air pollution which had killed off lichens and blackened urban tree trunks and walls. So now it was the pale form of themoth that was more obvious to predators, while the melanic form was better camouflaged and more likely to survive and produce offspring.

Answer:

The correct answer would be human-induced environmental changes.

Step-by-step explanation:

The natural selection of the peppered moth is a metamorphic event of a color change in the moth population. It was a result or aftereffect of air pollution during the Industrial Revolution.

Coal fires and industrial revolution cause heavy air pollution. In result, lichens get killed and trees become darker that leads the natural selection of these months.

Thus, the correct answer is human-induced environmental changes.
