The correct option is C

positive integer

Explanation for the correct answer:

A rational number is said to be a number which can be expressed as the ratio of two integers.

The standard form of a rational number is $\frac{p}{q}$ where,

$p,q$ are integers.

$q\ne 0$

$p$ can be positive, negative or zero. $q$ must be a positive integer.

Hence, the denominator is always positive in the standard form of a rational number.
