A. | Zine |
B. | Mercury |
C. | Cadmium |
D. | Tin |
Answer» A. Zine | |
Explanation: Galvanization is the process of applying a protective zinc coating to steel or iron, in order to prevent rusting. In current use, the term refers to the coating of steel or iron with zinc. This is done to prevent rusting of the ferrous item. The value of galvanizing stems from the corrosion resistance of zinc, which, under most service conditions, is considerably greater than that of iron and steel. |
