Answer:
OPTION D: Identity property of Addition.
Step-by-step explanation:
In addition, the identity element is the element, 'e' which when added to any element in the set does not alter the value.
We have, for an element 'a',
a + e = a = e + a
So, here, 0 is added to -7 and the value is not changed.
i.e., - 7 + 0 = - 7
Hence, 0 is the identity element of addition.
Note that 1 is the identity element of multiplication.
