The correct option is A0
The additive identity property says that if you add a real number to zero or add zero to a real number, then you get the same real number back. The number zero is known as the identity element.
Then zero(0) is the additive identity of a real number and all rational numbers are real.
Hence, 0 is the additive identity of rational numbers.
