Answer:
I think the Answer is B.
Step-by-step explanation:
Because C and C re easy to cross off and if Pedro were to make a movie in his mind wouldn't that distract him from other things like what if in the middle of reading in the class he starts making a movie in his mind he wouldn't pay attention to what others or the teacher is saying and would probably fail a test a a question about that subject since he didn't pay attention.
I hope this helps. :)
