  B) Aluminum oxide is insoluble in water and thus forms a protective coating that prevents continued oxidation of the aluminum.
  C) Aluminum oxide is even stronger than aluminum.
  D) The oxidation of aluminum is a very slow reaction, taking hundreds of years before any structural changes are noticed.
