A number of the form p/q is said to be a rational number if
(a) p and q are integers
(b) p and q are integers and q ≠ 0
(c) p and q are integers and p ≠ 0
(d) p and q are integers and p ≠ 0 also q ≠ 0

Solution:

According to the definition of rational numbers, it should be in the form of p/q and the denominator should not equal to 0

Therefore, q ≠ 0

✦ Try This: A number not in the form p/q is said to be (a) a irrational number, (b) an imaginary number, (c) a rational number, (d) a natural number

A number not in the form of p/q is called irrational number
