0%.
Assume this question has a correct answer.
If the correct answer appears 1 times on the possible answers then its probability should be 25%. Cannot be since 25% appears twice
If the correct answer appears 2 times on the possible answers then its probability should be 50%. Cannot be since 50% only appears once.
No answer is repeated 3 or 4 times.
So if the correct answer appears 0 times on the possible answer then its probability should be 0%. 0% does not appear on the possibilities so it is the correct answer.
