Which of juliet’s lines best shows that she understands romeo’s identity?
a. you kiss by the book.
b. my only love sprung from my only hate!
c. it is an honour that i dream not of.
d. but no more deep will i endart mine eye

B.My only love sprung from my only hate!

In this line by Juliet she is saying that the person she loves is someone she hates. The only family she is supposed to hate are the Montagues. The Capulets (Juliet's family) is feuding with the Montagues (Romeo's family). This reveals that Juliet knows that Romeo is a Montague.

"You kiss by the book" is a reference to the Bible. In their conversation, Romeo suggests that lips do what hands do by praying. In this way, he convinces Juliet to kiss him. Option C refers to Juliet's answer to her parents about Paris's proposal of marriage. Option D is when Juliet tells her mother she will only let herself have feelings for Paris if they give her permission.
