Correct Answer: Zinc

Solution : The correct option is Zinc .

Zinc is the most widely used metal in galvanisation. Galvanisation means coating iron or steel with a protective zinc coating to prevent corrosion. The zinc coating functions as a sacrificial anode, preferentially corroding to protect the underlying metal from rust and other types of corrosion. This method is extensively employed in different sectors, including construction, automotive and manufacturing, to extend the life and durability of metal items exposed to hostile conditions.
