Answer:
Option C is correct
a + 0 = a
Step-by-step explanation:
Additive identity:
For any real number x,
[tex]x+0 = 0+x = x[/tex]
We have to find an example of the additive identity from the given options.
Option A.
a+(-a) = 0
Which does not follow the additive identity.
Option B.
a+0 = 0
which does not follow the additive identity.
Option C.
a+0 = a
this equation follows the additive identity.
Therefore,an example of the additive identity is, a + 0 = a
