Correct answer: C. Oxidised
- A. Converted to a fine powder
- B. Reduced

- D. None of these
Explanation
Rusting involves iron reacting with oxygen and water to form hydrated iron oxides, so iron loses electrons and is oxidised. Reduction occurs simultaneously at the cathodic regions, but iron itself is oxidised.
