I choose the third one. It’s the only one that makes sense to me.
Hello, I could probably answer it more surely if the question was provided in its original format. But for how it was presented, I believe the answer would be C. A callout.
A callout (or call-out) in publishing is a short excerpt within a bigger text, somehow highlighted to call the reader's attention out to that part, specially. It can be a short string of text with its words connected by lines, dots, arrows, or similar, a sentence in bold separated from the text, or written in a different format, usually in a larger font. - This one is very common in magazines and newspapers. (and I believe this is the type that was presented on this excerpt original format).
Its i think B... adverb would be the time or place or circumstances...
D) find a meter that sounds like a metronome.
(Hope I could help! Let me know if I made a mistake!) :)
