Answer 2

The answer is Iron. [option (iii)].

• As we all know, Iron has the property of rusting.
• Rusting is a slow process where the metals present get decomposed in air and the protective surface on Iron gets vanished by which the iron gets rusted.
• When Iron is exposed to air or moisture, the above process occurs.
