I myself haven't read or watched Titanic. But I think the answer is either B or D. You should try to find the answer among these two. Good luck!

B-The word "love" appears five times in that note.
D- I often forget to cross my "t's" when I'm writing quickly.
2) </span><span>t would be "A" because the rest are incorrect by saying the name of something then not putting italics</span>
