class 8 chapter 1 of maths mcq test in chapter test section Q.2 answer is wrong. it should be a) instead of c).
The provided answer is correct.
The additive inverse of a number "a" is "–a", because when on adding a with –a, we get 0, which is the additive identity.
So, the additive inverse of 0 is –0, which is same as 0.
Thus, the additive inverse of 0 is 0.
However, the the multiplicative inverse of 0 does not exists as division by 0 is not defined.
Hope now it will be cleared to you.
