Imagine that I say the following, "In the Trolley Problem, you are faced with a forced choice: let five die or kill one to save five. All things considered, what you ought to do is kill one to save five. But, of course, killing is always wrong. So, despite this, killing one to save five is wrong. It's not the right action to perform." I've made a mistake. In fact, given the way we explained certain terms in class, what I've said is incoherent. It doesn't really make any sense.

Why is it incoherent?

A. Because only a Kantian would say that killing is always wrong and we can't assume that Kantianism is true.
B. Because if an action is, all things considered, what you ought to do, then it is right.
C. At least two of the other answers correctly explain why what l've said is incoherent.
D. Because there is no right answer to what we ought to do in the Trolley Problem. It is just a matter of opinion.
