The correct option is:
4. O, bid me leap, rather than marry Paris, / From off the battlements of yonder tower
In this line, Juliet claims she would rather leap from a tower than marry Paris. While her Character at the beginning was obedient, shy and innocent, by the end of the play she has become passionate, disobedient, courageous and faithful, because of her meeting and falling in love with Romeo. Her explanation to Friar Lawrence of how she would do anything to stay with Romeo is the best example of her new courageous and faithful persona.
