Which is an example of Identity Property of Addition? \( \begin{array}{ll}4.3 \times 1=3 & \text { B. } 9+7=7+9 \\ 42 . ~(7+3)+2=7+(3+2) & \text { D. } 5+0=5\end{array} \)

The Identity Property of Addition states that when you add zero to any number, the result is that number itself. In other words, for any number \( a \), the equation \( a + 0 = a \) holds true. Now, let's analyze the options provided: - **A.** \( 4.3 \times 1 = 3 \) (This is not related to addition.) - **B.** \( 9 + 7 = 7 + 9 \) (This demonstrates the Commutative Property of Addition.) - **C.** \( 42 \cdot (7 + 3) + 2 = 7 + (3 + 2) \) (This is not related to the Identity Property of Addition.) - **D.** \( 5 + 0 = 5 \) (This is an example of the Identity Property of Addition.) Thus, the correct answer is **D. \( 5 + 0 = 5 \)**.
