The correct answer is **d. All of the above**.
Each of the expressions demonstrates the Commutative Property of Multiplication, which states that changing the order of the factors does not change the product. Hereβs how each expression illustrates this:
- **a.** \(7 * x * 3 = 3 * 7 * x\) shows that the order of \(7\), \(x\), and \(3\) can be changed without affecting the product.
- **b.** \(4 * y * 2 = 4 * 2 * y\) shows that the order of \(4\), \(y\), and \(2\) can also be rearranged.
- **c.** \(5 * z * 6 = 6 * 5 * z\) illustrates that rearranging \(5\), \(z\), and \(6\) yields the same result.
Therefore, all provided expressions correctly demonstrate the Commutative Property of Multiplication.
