I believe the answer is A. I went over details about this play 2 years ago and I remember that in the movie and script, Juliet had expressed herself outloud on her balcony not knowing that Romeo had been listening and was rather hesitant with him after learning that he was there watching her because now he knew about her feelings but she did not yet know about his or whether or not he meant all of his "sweet-talking" words. In fact he had to reassure his love for her several times after.
Answer:
Romeo is implying that if Tybalt had obeyed the prince's orders, lives would be pulped, including his.
Explanation:
Romeo expresses how disobedience is evil and promotes pain and suffering. He reinforces that the prince had banned street fights, but Tybalt insisted on disobeying causing very negative results and that caused his own death, the death of Mercutio and exile of Romeu, who had to abandon his family and wife before being killed.
