Molten rock capable of fluid flow; called lava above the ground.

Explanation:
Molten rock that is still underground and able to flow is termed magma. The surface version of that material, once it erupts onto the land or sea floor, is called lava. So the description of molten rock while it’s below the surface fits magma best. Lava describes the material above ground, melt is a general term for melted material and not a specific name for the underground state, and volcanic rock refers to the solid rock that forms after the lava cools.
