Answer and Explanation :-

Answer: Option 3

Explanation:

Galvanisation is a process of coating iron or steel with zinc in order to provide greater protection against corrosion for the iron or steel base. Galvanised iron sheets are coated with a layer of zinc to help the metal resist rusting of iron. Zinc is used as a coat because it is far more corrosion resistance to iron and steel.
