None of the above.
A rational number is defined as any number that can be expressed as a fraction, where both the numerator and denominator are integers and the denominator is not zero.
The square root of 169 is 13, which is a rational number because it can be expressed as 13/1.
The square root of 17 and the square root of 3 cannot be expressed as a fraction, so they are irrational numbers.
