Solution

The correct option is B
Zinc

Rusting of iron takes place in the presence of oxygen, moisture present in the air. A coating of zinc is deposited on the iron to protect it from corrosion and formation of rust. The layer of zinc prevents oxygen from further reaction with the iron, making the iron object last much longer.
