The answer to your question is A
The seafloor spreading occurs at the mid-ocean ridges. The reason for this is that the convection currents from the mantle manage to break through the oceanic crust and propel magma on the seafloor. As they do, the magma consolidated in the water and new crust is created. Since there's constant pilling up of new crust, it pushes the old crust away in both sides. This results in the movement of the plates, and as they move eventually they will come into a situation to collide, resulting in the continents to start merging with one another. As the continental masses merge, they will gradually create a supercontinent.
