Solution
The correct option is B Zinc
To protect the iron from corrosion and rust, it is coated with zinc. Rusting of iron is an oxidation process in which iron gets oxidized in the presence of air and moisture for a long period of time. It is protected by applying a coat of zinc. The zinc protects iron by corroding first, i.e zinc oxidizes before iron metal thus preventing it from rusting.
Therefore, option C is correct.
