In the galvanizing process,iron is coated with zinc. The resulting chemical protection is most similar to that provided when

Given below are two statements:
Statement $I$: Corrosion is an electrochemical phenomenon in which pure metal acts as an anode and impure metal as a cathode.
Statement $II$: The rate of corrosion is more in alkaline medium than in acidic medium.
In the light of the above statements,choose the correct answer from the options given below:

The metal that forms a self-protecting film of oxide to prevent corrosion is

When iron undergoes corrosion,it .........

Explain: Corrosion of $Fe$ is a galvanic cell-like arrangement.

During galvanization of iron,which metal is used for coating the iron surface?
