Melting is a metamorphic process. Thus, the correct option is C.
Increases in temperature, pressure, and chemically active fluids forms metamorphism, which transforms existent rocks into new forms. Igneous, sedimentary, and other metamorphic rocks may be affected by metamorphism.
Movements in the earth's crust pull the rock down, and it gets hotter and hotter as it goes deeper. A rock melts at temperatures between 600 and 1,300 degrees Celsius (1,200 and 2,400 degrees Fahrenheit), transforming it into magma (molten rock).
