Yes you are also correct on it being B. because as you can see in the paragraph, it is listing the chronological order of the talent show acts from first to last. It would make sense for the paragraph to end with the final act which is option B. Hope I helped!
Yupp i think its B too. It wouldn't be A or B, because they were talking about the order the students came out. Therefore, A and C are off topic, and it wouldn't be D either because why would they talk about something out of order, when they are listing or talking about the order of the talent show? That just defeats the wole purpose of the paragraph.
