Answer:</h2>
Option: B is the correct answer.
B. Identity Property of Addition.
<h2>
Step-by-step explanation:</h2>
We know that identity under addition is the element which when added to any elements gives the resultant as the same element.
i.e. if e is the identity of the set then,
a*e=a for all a belongs to the set, where * is the operation
We know that under addition operation the identity is the zero element.
Because if zero is added to any element than it gives the same element.
Reason. 1 -d+(d + e)=(-d+d)+e 1. Associative Property of Addition.
Reason 2 = 0 + e 2. Additive Inverse Property.
Reason 3 = e 3. Identity Property of Addition.
