Answer 2

Answer:

Metals like platinum, silver, and copper are at a lower position in the reactivity series and are less reactive than iron. If a protective coating of platinum, silver, and copper is applied to iron, they won't be able to prevent corrosion as they are less reactive. Moreover, using these metals will not be cost-effective.

But, zinc is placed above iron in the reactivity series and, so it is more reactive. It gets oxidized before the iron object and thus protects it from rusting. Also, it is cost-effective
