Answer:
The correct answer is Friar Lawrence .
Step-by-step explanation:
What triggered the tragedy in this work was the actions of Friar Laurence. The plan that he had was carried out very quickly, which caused Romeo to take his own life.
Friar Laurence wanted Juliet to marry Paris, and he gave her to drink a liquor that would make her look dead on the outside, but she would actually be "asleep". This would cause her family to take her to the vault where after 42 hours she would wake up and could flee with her beloved Romeo. But because he hastened the plan, Romeo did not receive his letter in time explaining everything that was going to happen. This caused Romeo to believe that Juliet died and took his own life.
