You are correct! The expression that correctly demonstrates the commutative property of addition is:
**D. \( x + 4 + 15 = 15 + 4 + x \)**
The commutative property of addition states that changing the order of the addends does not change the sum. In option D, the order of the numbers is rearranged, which illustrates this property.
