Answer:
The correct answer is:
Protagonist: Romeo and Juliet
Antagonist: Capulet and Montague family
Step-by-step explanation:
The protagonist is the main character in a story, a leading and key figure of a story in each literary work.
On the other hand, the antagonist is a character who fights against the protagonists and it is often represented as a bad person or villain.
Romeo and Juliet are the main characters of Shakespeare’s tragedy, while their families could be considered as the antagonists because they had a big influence on the tragic ending of their love story.
