(B) Galvanization is the process of applying a protective zinc coating to iron or steel to prevent rusting.$Zn$ is used for this purpose because it acts as a sacrificial anode,protecting the iron even if the coating is scratched,due to its more negative standard reduction potential $(E^o = -0.76 \ V)$ compared to iron $(E^o = -0.44 \ V)$.
