Which of the Following Options Is the Best COUNTEREXAMPLE to the General

Which of the following options is the best COUNTEREXAMPLE to the general claim that:
The right thing to do in a situation is always to treat another person in the way you would want to be treated in that situation.

A) Imagine a vain man who loves it when strangers on the street whistle at him and complement his physical appearance. The fact that he would like to be treated this way does NOT mean he should treat other people this way. Most people find this behavior harassing and demeaning.
B) If you were a stranger visiting a new town, you would want the people there to be kind to you and to help you find your way around. That's why when you see a stranger visiting your own home town, you should be kind to them and help them find their way around.
C) Almost every religion makes some version of this claim. It is probably true
D) Suppose you are on your way to class and you see someone collapse on the sidewalk. It is true that if you were in their situation, you would want someone to help you. But this doesn't give you a reason to help that other person if you don't want to. It depends on whether or not you care about being late to class.
