How did you put this in English section?????

It's to show an exception (which is often the purpose of "yet") because in the first clause it identifies an action, then then it's like "but wait, maybe the action didn't really get going" in the second half of the sentence
The only conjunction in this sentence is C) but.
All of the other options are prepositions, not conjunctions.
