• A. 2 and -2
• B. -2 and 2
• C. 2 and 2
• D. -2 and -2

Answer 1

The correct option is B -2 and 2

Additive inverse of a number 'a' is defined as the number which when added to it yields zero.

Hence, additive inverse of 2 is -2.
Since, 2 + (-2 ) = 0

Similarly, additive inverse of -2 is 2.
Since, (-2) + 2 = 0
