Answer:
a. She cannot speak badly of Romeo.
d. Her allegiance to her husband (Romeo) is more binding than her allegiance to her cousin (Tybalt).
Step-by-step explanation:
Juliet is obviously conflicted between her love for Romeo and her fidelity to her family when she discovers that Romeo killed Tybalt, her cousin, in this scene. In the end, she makes the decision to refrain from criticizing Romeo and realizes that her devotion to her husband is more important than her loyalty to her cousin Tybalt.
