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?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

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 :-))
