Best answer
Right choice is (c) Copper

Explanation: Magnesium and zinc are highly active. Hence, they corrode at a faster rate than iron. Iron undergoes rusting in the presence of oxygen and moisture. Copper, a noble metal that occurs naturally in its elemental form, is almost totally impervious to corrosion.
