A. Liquid magma from the mantle rises to the surface.


The phenomenon described in the statement is related to plate tectonics and the movement of tectonic plates. As the plates move apart, magma from the mantle rises to fill the gap, solidifies and creates new crust. Therefore, option A is the correct answer.
