Final answer:
Romeo and Juliet were forced to hold secret meetings because of the parents' feuding. Option a is correct.
Step-by-step explanation:
The correct answer is a. Secret.
In William Shakespeare's play Romeo and Juliet, the two young lovers are from feuding families, the Montagues and the Capulets. Due to the animosity between their families, Romeo and Juliet are forced to keep their relationship a secret. They hold secret meetings to see each other without their parents' knowledge.
For example, in Act 2, Scene 2, Romeo sneaks into the Capulet's orchard and meets Juliet on her balcony under the cover of night. This secrecy is necessary because their parents would disapprove of their relationship and could even forbid them from seeing each other.
So option a is correct.
