Answer:
I would pick A. C is also possible.
Explanation:
It is much easier to start with what he does not mean.
E definitely is not what he means. He is not thinking of benefitting himself at all.
D is also not what he means. He does not intend to dwell on past mistakes: he is determined to learn what he did wrong and what he can do to improve.
C is possible. Let's just go on.
B there is no pretense in his fear. Those spirits have done their jobs well. Scrooge is scarred out of his wits that what they have shown him may actually come to pass. His worst nightmare is that he can do nothing about it.
A is possible. So now you have to choose between C and A.
It could be either A or C. I'd pick A myself because it is an action. It's a plan.
I usually tell people when it is this close that either could be right. Just because I say it is so, does not make it so. If you have strong feelings about C, pick it.
