               D. Identity Property of Addition
<h2>
Step-by-step explanation:</h2>
We know that an identity is a value which when added to any element of the set gives the resultant as the element itself. 
Also, we know that the identity under addition is always: zero.
Because when zero is added to any number then the resultant is the number itself i.e. adding zero does not affect the value.
Hence, by the Identity Property of Addition we have:
                               0 + x = x
