The correct response would be:
disruptive selection; two peaks at the extremes of the graph with a dip in the middle.
In the case of peppered moths, light and dark moths are favored in different environments (light-colored moths in light environments and dark-colored moths in dark environments). This leads to a distribution curve that has two peaks (one for each color) and a dip in the middle, characteristic of disruptive selection.
