Answer 1

The correct answer is: The dark-colored moths became more common.

During the Industrial Revolution in Britain, pollution darkened the surfaces of trees and buildings, making light-colored peppered moths more visible to predators. As a result, dark-colored (or melanic) moths had a survival advantage and became more common in the population.
