Attached is the illustration

The answer is a. hot spot

Explanation:

A hot spot is an area of the surface of the Earth with volcanism. It is thought that they are caused by very hot temperatures in certain areas of the earth's mantle compared to the surrounding mantle causing magma to rise from under the mantle and through the lithosphere. This is called a mantle plume.

Since the earth's plates move along, the magma keeps pushing up from under the mantle and creates another volcano. This is called a hotspot track.

What we see in the picture is a second volcano being created next to an older one in the same area, and magma is pushing up from underneath. This matches with the description of a Hotspot
