Marked option-C is correct. Earth have internal heat energy which drives plate tectonic processes. In order to drive tectonic plates, internal heat engine is required. In case of Earth, Mantle convection currents drive the plates and lead to the formation of different plate boundaries (convergent, divergent etc.)

Your answer is correct... All other concepts are not vital in case of tectonic activities to take place. Internal energy is what that is provided for the tectonic plate movement and mantle convection is the key player in this plate movements. You can go through various sites dealing with whether the plate tectonics prevailed on various planets in the past or not (Need not go for the jovian or gaseous planets as they don't have solid or rock foundations to even stand upon like various great dark spot on neptune and red spot on jupiter having high speed winds).
