The negative of a non-zero rational number is:

Correct option is C

The correct answer is (c) a rational number. Explanation: •A rational number is a number that can be expressed as the ratio of two integers, where the denominator is not zero. Examples of rational numbers include 1/2, -3/4, 5, etc. • The negative of a rational number is obtained by multiplying it by -1. For example, if the number is 3/5, its negative is -3/5, which is still a ratio of two integers and hence remains a rational number. • Therefore, the negative of any non-zero rational number is still a rational number.
