True or False?

Question: True or False? The answer to this question is false.

1. True
2. Both answers would work
3. False
4. Neither answer would work

Answer is Neither answer would work. 

This question creates a paradox because neither answer would be correct. If the statement were true, that would be implying that the answer would be marked as false. This would then state that the statement is false, but since the statement says the answer is false, answering false would make the statement true.
