D. 4
In the balanced chemical equation, the coefficient in front of Al is 1, which means there is 1 Al atom involved in the reaction. On the product side, we have (Al2 O3)4, which means there are 4 molecules of Al2 O3. Since each molecule of Al2 O3 contains 2 Al atoms, we can multiply 4 by 2 to get the total number of Al atoms on the product side:
4 x 2 = 8
Therefore, there are 8 atoms of aluminum on the product side. The correct answer is D. 4.
