Answer:
The lines that foreshadow Romeo's tragic end are found in option 4:
O God, I have an ill-diving soul!
Methinks I see thee, now thou art below,
As one dead in the bottom of a tom
Either my eyesight fails, or thou look'st pale!
Explanation:
"Romeo and Juliet" is a famous tragic play by William Shakespeare in which two young lovers die due to the rivalry between their families. At several points in the play, Shakespeare uses foreshadowing to reveal the tragic ends that await the characters. Foreshadowing is a technique in which a piece of information is given to the audience that will later unfold into something important, however trivial it looked at the beginning. The lines above are said by Juliet, and she seems to be aware of her own ability to predict. She looks at Romeo and sees a dead body, which foreshadows his end.
