Answer

Answer:

C. expanding gases

Brief Explanations:

Magma contains dissolved gases. As magma rises, pressure decreases, causing gases to expand. This expansion creates force to push magma through volcanic structures. Gravity pulls downward, water flow isn't the main force here, and convergent boundaries relate to plate movement (not directly the force pushing magma). So expanding gases is the cause.
