The correct answer is - C. hot spots in the mantle.
The Hawaiian Islands are a volcanic islands. They are lying above a hot spot. The hot spot volcanoes, unlike the other ones, are far away from the boundaries of the tectonic plates and they are emerging on places were there's hot spots. These hot spots manage to penetrate through the crust and get the magma from the mantle up to the surface and create volcanic islands in meantime.
The enormous submarine canyon located off the coast of central California in Monterey bay is very well studied for both its geologic and biologic features, as well as being a national marine sanctuary. Thus, "Monterey" is the correct filler to be used here.
<h3>What is a Submarine canyon?</h3>
A submarine canyon is a steep-sided valley that has been dug into the seabed of the continental slope; it can occasionally extend deep over the continental shelf, have virtually vertical walls, and can have canyon walls that are up to 5 km high, like the Great Bahama Canyon. Submarine canyons provide routes for the movement of turbidity currents over the seafloor, just like above-sea level canyons do for the movement of water through land.
Rivers may provide turbidity currents or storms, and undersea landslides, earthquakes, and other soil disturbances may create them on the seafloor. Turbidity currents are movements of water that are thick and sediment-laden. The continental slope is eroded by the swift (up to 70 km/h) turbidity currents that flow downslope.

Answer:
This passage is mainly about asteroids striking Earth.
Explanation:
The presented passage is mostly focusing on asteroids striking Earth. It is something that has been happening since Earth has formed, and it will happen in the future as well. The vast majority of the asteroids don't really have any impact on Earth, but some have an impact that is devastating and long-lasting.
In the earlier stages of Earth, many more asteroids were falling on the surface, and the main reason for that has been the lack of atmosphere or a very thin atmosphere. As the atmosphere started to take shape and became similar to what is nowadays, the asteroid impacts decreased significantly because the atmosphere was managing to burn them and break them apart. This is not possible with all asteroids though, as some are so big and fall under an angle where the atmosphere doesn't really have any impact on them so when they fall on the surface they are able to cause sudden climatic changes, mass devastation, and mass extinction of species. Such an asteroid will be in a direction to hit Earth in the future for sure, the question remains will humans with their technology be able to prevent an impact or not.
