Answer 1

The correct response is:

disruptive selection; two peaks at the extremes of the graph with a dip in the middle

This is because in different environments (light vs. dark), light moths are favored in light environments and dark moths in dark environments, leading to a situation where both extremes are selected for, resulting in a bimodal distribution (two peaks) in the population.
