Riddle 4 is a variant of the liar paradox and thus cannot be given an answer.
Proof by contradiction:
Assume the riddle has an answer. Then, by the riddle itself, it wouldn't be the answer. This is a contradiction (something can't be both the answer, and not be the answer at all), so the riddle cannot have an answer.
