Question

Which of the following represents additive identity?

• A. 2 + 0 = 2
• B. 2 - 1 = 1
• C. 4 × 2 = 8
• D. None of the above

Answer 1

The correct option is A 2 + 0 = 2

For any integer 'a', if we add 0 to that number, we get the same number as the result.
i.e., a + 0 = a, where 0 is the additive identity.
Hence, option a is the correct answer.
