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.
The main purpose of seeds is to carry out reproduction so that the plants can perpetuate themselves. After pollination and Fertilization the seed formed has the capacity to germinate into an adult plant over time. It has all the necessary nutrients and food sources required for a plant to germinate and are also modified for different species to allow for further dispersal so the plant can spread more easily to better growth conditions.
