Question

in act iii, scene 5, lady capulet thinks that juliet is weeping for tybalt when she is actually weeping for romeo. the dramatic irony —
implies that lady capulet does not understand love
proves lady capulet disapproves of the continued violence
shows the audience the double meaning of what juliet says
provides the audience with evidence that lady capulet knows juliet has married

Explanation:

Dramatic irony occurs when the audience knows more than a character. Here, the audience understands Juliet's true grief is for Romeo, while Lady Capulet misinterprets it as grief for Tybalt. This lets the audience recognize the double meaning in Juliet's words, which Lady Capulet misses. The other options are incorrect: there's no evidence Lady Capulet doesn't understand love, she supports violence against Romeo, and she does not know Juliet is married.

Answer:

shows the audience the double meaning of what Juliet says
