The statement that best explains mantle convection is:

Cooler material in the mantle moves down, and warmer material in the mantle moves up.

This process creates a convection current, where the heat from the Earth's core causes the mantle material to warm, rise, cool down as it moves away from the heat source, and then sink back down.
