Answer:
The correct answer is 2. He wants to save Juliet from Paris and has no other way to do it.
Explanation:
Lord Capulet wanted to marry Juliet to Paris. But she refused to do it. And Capulet threatened to disown her. Juliet went to Friar Laurence to get some advice. He came with only one idea to help her and it was to give her a potion that will make it seem like she is dead, but the potion will be used to make her sleep for a while. And Romeo would come for her. So the most suitable option is that Friar wanted to save Juliet from Paris.
