What is the role of oxides in the formation of rust?

• Oxides facilitate the corrosion of iron, leading to the formation of rust.

• Oxides are not involved in the rusting process at all.

• Oxides prevent the corrosion of iron, stopping rust formation.

• Oxides only affect non-metal materials, not iron.
