Correct Answer: Option 2 – heat energy has been creating convection currents in the Earth's interior

The tectonic plate movement occurs due to the heat energy creating convection currents in the Earth’s interior.

It is not the gravitational force of the moon, or the earth’s rotation on its axis or the change in the tilt of the axis of the earth which has lead to the tectonic plate movement. Hence, options 1, 3 and 4 are incorrect.
