C would be the best, because it is the one that starts a discussion about the art and not just the museum. It also does not sound aggressive about liking the art himself. Hope this helps!
He's trying to explain what exactly motivated him, particularly in the second paragraph. It was none of the things that would motivate someone to commit murder. Gain of any kind was out of the question. Feelings were not the motive. Nothing the old man had motivated him.
It was just his eye. So he's in a battle with himself. (That's the first answer).
We are leading up to something and we need to have a background. This is not the climax or the resolution. It is not the falling action -- just the opposite. It is the build up towards the climax.
So the only thing it can be is the exposition which is the second answer.
Buddy no one is going to read that much im just saying and if you find someone that answers the question he is on some CRACK!!! so just do it by yourself
