Is this problem right?

I keep getting an answer for this problem that isn't one of the choices offered. I reported an issue but didn't hear back. Maybe I'm just wrong?

I do not see that you reported this question. I've received reports from you on other questions. I see only 1 report for this question (from another member) which merely states what he thinks the answer is.

Judging form the solution which was written by someone else, the answer does look wrong. I have added a banner to the problem.

Thanks! I guess the report never submitted successfully. Probably user error. I was also objecting to the confusingness of "if any two variables don't have the same value", which could be read as all three are distinct, or there exists a pair that are different (e.g., they can't all be the same). I tried to solve it both ways and still didn't get one of the choices. :-) Any way we can just fix the problem to not be multiple choice and expect the right answer? (I don't like the multiple choice ones anyway :-))
