Correct answer: B

Corrosion slowly coats the surfaces of metallic objects with oxides or other salts of the metal. The rusting of iron, tarnishing of silver, development of green coating on copper and bronze are some of the examples of corrosion.

$\bullet$ Production of H$_2$ by electrolysis of water is an example of electrolytic cell.
