Answer

Answer:

C. expanding gases

Brief Explanation:

Magma contains dissolved gases. As magma rises towards the surface, the pressure decreases, causing the gases to expand. This expansion generates the force that pushes magma through the volcanic pipe and vent. Gravity would pull magma down, water - flow is not the main factor, and convergent boundaries are related to plate tectonics but not the direct force for magma movement from the chamber.
