Solution

The correct option is D

All of the given options


Rusting of iron can be prevented by painting, oiling, greasing, galvanizing, chrome plating, anodizing or making alloys.

Through galvanisation, painting and chrome plating, the surface of the metal is no longer exposed to the atmosphere, and thus, corrosion is prevented.
