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.
