Solution

The correct option is D E(Zn2+/Zn)<E(Fe2+/Fe)
Zinc is used for coating iron to prevent rusting because whenever the metal comes in contact with moisture and water then there is formation of electrochemical cell and oxidation of metal takes place, zinc is having lower reduction potential and acts as anode and oxidation of zinc take place rather than iron so, in this way we can prevent iron from rusting.
