Answer

Brief Explanations:

Igneous rocks form from the cooling and solidification of magma or lava. Metamorphic rock must be pulled under Earth's crust, melted to form magma, and then forced out above the crust to cool and become igneous rock. Option A describes the process of forming metamorphic rock from other rocks. Option B is not a process for forming igneous rock. Option D describes the process of forming sedimentary rock.

Answer:

C. It must be pulled under Earth's crust, melted, and forced out above the crust to cool.
