Which is the best explanation for why -\sqrt{10} is irrational?

-\sqrt{10} is irrational because if I put -\sqrt{10} into a calculator, I get -3.16227766, which does not make a repeating pattern.

-\sqrt{10} is irrational because it is not rational.

-\sqrt{10} is irrational because it is less than zero.

-\sqrt{10} is irrational because it is not a whole number.
