Why the answer is C, and why the others tempt you.
Under intense heat and pressure, limestone is metamorphosed into marble, while shale is metamorphosed into slate. These are the correct parent rock–metamorphic rock relationships. Quartzite is the metamorphic equivalent of sandstone, not limestone or shale.
