Is it possible through five odd numbers to add 20?

Answer

Yes: 1+1+5+13=20

Here are three answers:
A. Answer A
B. Answer A or B
C. Answer B or C

There is only one correct answer to this question. Which answer is this?

Answer

If answer A would be correct, then answer B ("Answer A or B") would also be correct. If answer B would be correct, then answer C ("Answer B or C") would also be correct. This leads to the conclusion that if either answer A or answer B would be the correct answer, there are at least two correct answers. This contradicts with the statement "there is only one correct answer to this question". If answer C would be correct, then there are no contradictions.

Therefore, the solution is answer C.
