Rusting of iron is related to which process?

Answer and explanation

Correct answer: Oxidation

Rusting is a chemical corrosion process in which iron reacts gradually with oxygen in the presence of moisture and forms hydrated iron(III) oxide, commonly called rust. Since iron combines with oxygen, the process is classified as oxidation. Freezing and melting are physical changes of state, while filtration separates substances without forming a new compound. Therefore, oxidation is the correct choice, so option A is correct.
