Answer:
Disruptive selection
Explanation:
According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.
From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.
According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.
Hope it helps, sorry for the late reply! have a good day :)

Divergent-Seafloor spreading can occur at Divergent Boundaries. Tectonic plates will slowly move away from the other, the heat from the mantles convection current will crust the plastic making it much way less dense and the less dense material will rise up and will often form a mountain or elevated area of the seafloor.
