Answer:

The correct answer is option A. "directional selection".

Explanation:

Directional selection is a type of natural selection at which traits with extreme characteristics are selected over traits with medium characteristics. In this case,  a long-term climatic change resulted in all seeds that are the fountain of food for finch becoming hard. This will result in a directional selection on bill size in the finch population, where large-billed birds will be selected over small and medium-billed birds.
