    Answer : Option C

    Explanation :

    Gold plating is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical plating. Electroplating of gold is done using a sulphate/sulphite based electrolyte. This product is environment- and user friendly and moreover the electroplating rate is good.
