A rational number is a number that can be expressed as a fraction or ratio (rational). The numerator and the denominator of the fraction are both integers.

so the square root of 169 is 13, correct?

The number 13 is a rational number because it's a whole number.

That means option A is not irrational, thus not the correct answer.

Option B is not irrational as well because that will give you 12. So is option C. That also gives you a whole number of 9.

12.5 is a rational number. That's a fraction with integers. The square root of 156 does not contain recurring numbers which means it's irrational.
