A and C are irrational.

We know that B is rational because it's just asking 8 - 5, which is 3.

There is, however, no perfect square root of 73 or 56, and so the answer will be irrational.

A and C are irrational because they are non-termininating decimals.

If you have any further questions feel free to ask.

Hope this helps.
