Which of the Following Options Is the Best ILLUSTRATIVE Example

Which of the following options is the best ILLUSTRATIVE example for the claim that:
It is morally permissible to cause someone temporary pain if that is the only way to save them from significant harm.

A) It was morally permissible for John Lithgow's to tell Harry to go away.
B) Imagine that you see a child playing in the street, about to be hit by an oncoming car. The only way you can save them is to physical tackle them out of the street and out of harm's way. It is morally permissible to cause that child temporary pain to save them from being run over.
C) It is true that causing pain to avoid serious harm is often morally permissible.
D) Imagine that you learn that your best friend is planning to go out to a rock and roll concert the night before she has an important presentation at work. You can see clearly that this is the wrong decision for her, but the only way you have to stop her is to lock her in your basement for the night, where you are confident she'll get a good night's sleep. It is morally permissible to cause her the temporary pain of missing the concert to save her from doing a bad presentation at work.
