The answer is; C

This is due to natural selection that is the basis of evolution. The light-colored moths became conspicuous to its predators in the dark environment. The black moths on the other hand camouflaged and were preyed on less. This allowed black moths to have an increased chance, compared to light-colored moths, of reaching reproductive age and passing their genes to the next generation.
