How is B correct?

How is B the correct answer? I understand the set up but I am not understanding how B is right. Thank you!

I find the easiest way to answer this sort of question is to knock off answers by process of elimination by simply applying them to the rule set.

Because there are no repeat offices in any of the answer choices, the only relevant rule is that each employee selects the office that he or she ranks highest among the unselected offices. So letâ€™s use that rule to look at answers.

You should notice right off the bat that the question is not telling you anything about the order of selection â€” so we have to figure that out via inference. In other words, is there an order that works and still follows our rule set?

Answer A: We know that Y is the first choice for J and P, and X is the first choice for L and T. Nobody picked their first choice, so we know this answer is wrong.
