How does seafloor spreading relate to supercontinents

The answer is A

Explanation:

Seafloor spreading causes continental plates such as the North American Plate and the Eurasian plate to move apart in the mid-Atlantic ridge. However, the movement of the plate can cause the plates to move towards others. Eventually, when the continental plates move together they form supercontinents. The convection currents in the mantle are the driving force under the tectonic plates.
