4. He has no motive because he is not giving her poison.
Explanation:
This is the most likely answer, as all the other options imply that Friar Laurence was indeed giving poison to Juliet. However, the friar only gave Juliet a potion that would make her <em>appear</em> dead, but would not actually kill her. The motivation for doing so was for Juliet to be able to avoid the wedding with Paris and instead run away with Romeo.
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.
