Which statement describes the identity property of addition?

Explanation:
Zero acts as the identity element for addition: adding zero to any number leaves that number unchanged. For any number n, n + 0 = n. This is exactly what the statement describes. The other options relate to different ideas: multiplying by zero gives zero, multiplying by one gives the multiplicative identity, and a + a = 2a expresses doubling, not the identity property.
