Which questions are statistical question? A. how many theaters are in my city?
B. how many students in my class like classic movies?
C. how many movies do the students in my class watch in a month?
D. how many students in my class watch movies on weekdays?

If it's multiple choice, I'd say B and D. If it's only one, those are the ones I'd narrow it down to.

Step-by-step explanation:

All you have to do is imagine the question's answers as a statistic. With A, you can't say "There are 56% theaters in my city." So that's out. C is the same, you cant say "The students in my class watch 47% movies in a month." Also out. Sorry if this answer is incorrect, but that's your best bet.
