The scenario described indicates that female reindeer are consistently giving birth to larger offspring over generations, which suggests that larger offspring have a selective advantage. This type of selection is known as directional selection.

In directional selection, the distribution curve for that trait would shift in the direction of the favored phenotype—in this case, larger offspring—over time. Therefore, the correct response is:

Directional selection; the curve would shift to the right.
