Answer:
B. Stabilizing selection
Explanation:
When natural selection acts against the extreme phenotypes but favors intermediate variants, it is called stabilizing selection. Stabilizing selection is mostly operative in the population s that are well adapted to the prevailing environmental conditions. Individuals with average or intermediate phenotypes are favored by stabilizing selection.
In the given example, the elk population maintains the antler size over generations. Most of the elks have intermediate-sized antlers while only a few have larger or smaller antlers. Since the average antler size (the intermediate phenotype) is favored over the extreme ones (larger or smaller sized antlers), the population is experiencing stabilizing selection.
