Which of the following best explains why electrometallurgy is a useful process in many industries?

A.) Electrometallurgy can etch permanent marks and designs into the surfaces of metal products.

B.) Electrometallurgy can create a thin film around metals, preventing rusting and other forms of corrosion.

C.) Electrometallurgy can refine a wide range of impure metals used in manufacturing, wiring, and many other applications.

D.) Electrometallurgy can split water molecules into a cheap source of oxygen gas that can be carried into space and beneath the ocean.
