Interjections are basically exclamations such as: 'Ouch! Wow!', etc. So the correct answer is D, an exclamation point (!).
I believe your answer is B. Benvolio and Mercutio cannot find Romeo. This adds suspense because of them not knowing where he is. This worries them, and causes them greif in what they think happened to him. It also causes paranoia. Hope this helped!
