Solution
The correct option is A Motion of molten magma inside the earth
Heat transport between the planet core and surface is very similar to hot water convection. The mantle is heated from below (the core), and in areas that are hotter it rises upwards (it is buoyant), whereas in areas that are cooler it sink down. This results in convection cells in the mantle, and produces horizontal motion of mantle material close to the Earth surface.
