The stable ionic compound resulting from the combination of aluminum and oxygen is \( \text{Al}_2\text{O}_3 \).
Aluminum has a charge of +3, while oxygen has a charge of -2. To balance these charges in an ionic compound, you need two aluminum ions (each with a +3 charge) to balance with three oxide ions (each with a -2 charge). The resulting formula is \( \text{Al}_2\text{O}_3 \).
So, the correct answer is:
**A. Al2O3**
