A propane tank inspector detected rust in a tank. The empty cylinder valve was not closed, and water vapor settled inside causing rust to form. The cylinder is unusable. Select the combination reaction for the formation of rust. A. Fe₂O3 → 2Fe + O₂ B. 4Fe + 3O₂ → 2Fe₂O3 C. FeCl₂ + H₂O → FeO + 2HCI D. Fe₂O3 + 3CO→ 2Fe + 3CO₂
