The correct answer is: Option (D) 6 aluminum and 9 oxygen!

Explanation:

Since the one molecule of aluminium and oxygen is Al2O3 (Aluminum oxide). It has 3 oxygen atoms and 2 aluminium atoms. It find the atoms for the 3 molecules, multiply them with 3.

3 * 3 oxygen atoms = 9 oxygen

3 * 2 aluminum atoms = 6 aluminum (Option D)
