Is zero a rational number?

Correct option is A. 1We know that, a rational number is a number which can be written in the form of p/q, where q is not equal to zero. Thus, yes, zero is a rational number, as it can be written in the form of p/q. Since 0 (zero) is an integer, zero can be written in the form of p/q. Example: 0/1, 0/2, 0/3, etc. where 0 (zero) is an integer.
