Solution

The correct option is A Both A and R are true and R is the correct explanation of A.
Electroplating involves coating the layer of a metal on another metal via electrolysis. Gold and silver are electroplated over artifical jewels to make them appear shiny, Zinc is usually electroplated over iron to prevent corrosion of iron. Tin is electroplated over steel in cans so as to prevent the reaction between iron and the food inside the can.
However, neutralising charges on the surface doesn't need electroplating.
