Name a common metal which is highly resistant to corrosion.

उत्तर
Aluminium is a common metal that is highly resistant to corrosion because it is a highly reactive metal. It reacts easily with oxygen in air and forms a layer of aluminium oxide on its surface. This aluminium oxide layer is very tough and does not allow air to enter the metal for further reaction, thus preventing further corrosion of aluminium.
