The correct answer is
None of these
The general process of coating a superior metal over an inferior one is called Electroplating; Galvanization is a specific case (zinc coating on iron/steel) and Electrolysis/Electrification are different concepts, so since 'Electroplating' is not listed, 'None of these' is the accurate choice.
