Answer Details
The presence of water and oxygen is required for corrosion to take place. When a metal is exposed to oxygen and water, a chemical reaction occurs that forms metal oxide or hydroxide, which weakens and breaks down the metal. Carbon (IV) oxide may also contribute to corrosion, but it is not a necessary component. Therefore, "Water and Oxygen" is the correct answer.
