The correct answer is c) Thrice. In William Shakespeare's play Romeo and Juliet, the Prince of Verona intervenes in the brawls between the Montagues and Capulets on three occasions. The first time is in Act 1, Scene 1, when he reprimands the two families for their constant fighting. The second time is in Act 3, Scene 1, after Mercutio and Tybalt are killed, where he threatens to execute anyone who disturbs the peace. The third time is in Act 5, Scene 3, when he discovers the bodies of Romeo and Juliet and admonishes the families for their feuding.
