    This looks pretty good, but it only proves the conclusion for one half of the author's binary. If insult is true, then it's useful information, and thus (according to this answer), anger is an unreasonable response. But ... what about if insult is false?

This answer choice is saying "anger would be an unreasonable reaction to Person Y", but the conclusion is saying "anger would be an unreasonable reaction to Person X".
