I believe none of these options are correct. However, if you had to choose one, I would pick A - <span>Nina slid into her seat just as the bell rang and tried to catch her breath.
B, C, and D are incorrect because these are all examples of direct characterization, meaning that the other directly tells us what these people are like. This doesn't happen in A, which is why I would choose that option.
</span>
C. Instance, because you are using a dash to separate the list from the rest of the sentence
My personal opinion to what the answers are:
Readers are uneasy with the narrator's growing instability,
Readers question the narrator's ability to act rationally,
Readers understand that the account given by the narrator is true.
I hope this helped, again, this is only my opinion to what I believe the answers are.

I hope this helps you!
