Answer

Answer:

C. Decreases the melting point

Explanation:

Step1: Recall rock - melting principle

Water acts as a flux in rock melting.

Step2: Understand flux effect

Fluxes lower the melting point of substances. In magma formation, water present in the rocks lowers the melting temperature of the rock material, making it easier for the rock to melt at lower temperatures compared to a dry - rock situation.
