This is pretty easy. You are only writing a review so I'm guessing you can basically write whatever.
I would start with the name of the film.
Then the short summary. (doesn't have to be long if you only have to do 120 words in total.)
Then where you watched the movie and who you watched it with. i.e I watched this movie on my couch with my mum.)
Then say whether you liked it or not.
And that looks to be all you need to do :)
Synonyms. Hope I helped! :)
You are correct in assuming that the answer is A. He is being thorough in running more tests.
