Mountains are formed as a result of tectonic activity. What justifies this inference? A. When two plates move away from each other, the scraping and piling up of huge amounts of sediments and rocks form mountains.

B. When two plates move toward each other, large amounts of molten magma flow to the surface between them to form mountains.

C. When two plates move toward each other, compressional forces bend the plates to form mountains.

D .When two plates move away from each other, both plates subduct near a fault line to form mountains.
