Which metal is electro-deposited on iron surface to prevent rusting?

Identify True $(T)$ or False $(F)$ for the following statements :
$(i)$ In electrolytes,current flows due to electron displacement.
$(ii)$ When current flows from metal,the composition of the metal changes.
$(iii)$ Due to the passage of $DC$ current through the electrolytic solution,a reaction occurs.
