Zero (0) is
(a) the identity for addition of rational numbers
(b) the identity for subtraction of rational numbers
(c) the identity for multiplication of rational numbers
(d) the identity for division of rational numbers

Solution:

We know that if zero is added to any rational number, it gives the same result.

Additive Identity means a number which needs to be added to a given number so that the result gives the same number.

Hence, zero is called additive identity of rational numbers
