If you choose an answer to the question, 'If you choose an answer to a question at random, with possible answers of A)25%, B)50%, C)60% or D)25%, what is the chance you will be correct?', what is the chance you will be correct?
The only answer you would get is B.
The only other argument you could have is it's never ending self-reference, therefore never being able to give an answer.
