Why is rusting of iron called slow oxidation?

Answer and explanation

Correct answer: Because iron reacts slowly with oxygen and moisture over time.

Rusting is an oxidation process because iron gradually combines with oxygen in the presence of moisture, producing hydrated iron(III) oxide, commonly called rust. The reaction occurs over a long period and does not show the rapid energy release of burning. Therefore, option B correctly explains why rusting is called slow oxidation; the other statements contradict the role of oxygen, moisture, or reaction rate.
