Answer:
a. The convective circulation in the upper mantle
Explanation:
The engine that powers plate movement is the formation of convective cells within the mantle.
Convection is a heat transfer method usually that occurs within fluids.
The internal heat engine provides a source of temperature that makes part of the mantle to occur in a weak molten form. This is the asthenosphere. Overriding the layer is the lithosphere.
Convection allows for dense and cold lithospheric plate to sink into the asthenosphere and the hot, buoyant asthenosphere rises to the surface to replace it. The alternation between these processes results in mantle convection and eventual plate movement.

The Von Thunen model has an epicenter which is the center of a settlement. The model shown has a center area and grows outward just like the Von Thunen model. All the important goods are closer together while the forest and non important goods are farther outward. The new map makes the assumptions of goods are carried out by railroads and the climate and soil quality are the same throughout the map but may vary depending on specific areas very much like the Von Thunen Model.
Hope this helps. I'm on this question too so I could be wrong but at least I tried.
