Derstrom,
It would be 100% with respect to the letters if you could select all four letters. It is 100% as far as being correct. But I choose to interpret it as being able to select at random, only one particular letter. You have a 25% chance of doing that. The answer will show us when it is disclosed.

I can definitely see where you're coming from, but I don't agree. If all of them had the same value of 25%, then the chance would be 0%, because the correct answer is not listed (100%). You would need to take it further in order to realize that none of the given answers are correct. In fact, i don't believe there would be any correct answer (at all)--it is undefined.
