2) disruptive selection

Explanation:

Disruptive selection is a type of natural selection that acts against less fit heterozygotes. The disruptive selection can be represented by a decrease in the variance of a trait. In this case, the disruptive selection eliminates the medium-sized beaks, thereby favoring the extreme phenotypes in an interbreeding population.
