The correct answer is option B) "stabilizing selection".

In this case at which sparrows with average-sized wings survive severe storms better than those with longer or shorter wings illustrates stabilizing selection. It its believed that this type of selection is the most commonly found in nature, since most traits have no extreme values in most of the species.
