The correct answer is - B. Pacific Ring of Fire.
The Ring of Fire, stretching on the outskirts of the Pacific Ocean, is the place in the world that by far leads in earthquake activity, by having around 90% o all the earthquakes in the world.
The reason for this is that the Pacific tectonic plate is surrounded on all sides by higher, lighter, continental tectonic plates, so it is subducting under them. By subducting under the continental plates, lot of high temperature, high pressure, and magma, are able to come to the surface of the Earth from the lower mantle layer, and that cause a lot of stress and disruptions on the crust, which results in earthquakes.
