Which equation demonstrates the Additive Identity Property?

Explanation:
Additive identity means adding zero to any number leaves it unchanged. Since adding zero doesn’t change the value, the appropriate equation is a + 0 = a. The other expressions don’t represent that property: a + 0 = 0 would force a to be zero, 0 - a = -a is about additive inverse, and a × 0 = a isn’t true since any number times zero is zero.
