C. Because if you have 2+6 and 3×4. Inverse property can inverse 2+6 into 6+2. With 3×4, you can change it into 4×3 and the solution/answer won't change. But if you have division or subtraction, then it won't work. Example: 5-4=1 but 4-5 doesn't equal 1. 14÷7=2, but 7÷14 doesn't equal 2. So that is why C. Inverse Property is the answer
