    Solution:

    The above statement is true. Rusting of metals is an oxidation process. It happens when metals like iron and copper react with oxygen and moisture in the air. A layer of oxide forms on the metal surface, known as rust. It is removed by using galvanization. It is a technique in which a layer of zinc is coated on the metal, which prevents the direct contact of metal with air.
