Which of the following best explains why electrometallurgy is a useful process in many industries? electrometallurgy can etch permanent marks and designs into the surfaces of metal products. electrometallurgy can create a thin film around metals, preventing rusting and other forms of corrosion. electrometallurgy can refine a wide range of impure metals used in manufacturing, wiring, and many other applications. electrometallurgy can split water molecules into a cheap source of oxygen gas that can be carried into space and beneath the ocean.

Here we have to choose the sentence which is most effective to describe the usefulness of the electrometallurgy process.

The sentence which can explain the effectiveness of the electrometallurgy process is- Electrometallurgy can create a thin film around metals, preventing rusting and other forms of corrosion.

In the electrometallurgy process the metal is used as a cathode or anode and the other metal is used as anode or cathode respectively. In the process the other metal makes a thin film on the metal surface as the electrolysis process is purely a surface active phenomenon.

The electrometallurgy is an uniformity process which cannot marks or make design specifically in one surface of the metal.

The electrometallurgy process is not applicable for refining a wide range of impure metals for manufacturing purpose. As it is only a surface related phenomenon.

There is no relation between the electrometallurgy and splitting of water to form oxygen gas, as it is not applicable for a wide range of electrolysis.  

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

Explanation:

Electrometallurgy is the process by which metals are created with the use of electricity, and it is created by electrolysis, this creates a thin film around metals, this protects the metals from rustig and corrosion, this is important for many producers because it gives more life spam to the products they product, making them more durable, this is why in it is an important process in many industries.
