It should be "have you?" for proper grammar. (2) "You haven't seen the film, did you?" - This option is incorrect because it uses "did you?" which is the past tense. The sentence is in the present perfect tense ("haven't seen"), so the question tag should match the tense, which is "have you?" instead of "did you?" (3) "You haven't seen the film, have you?" - This option is correct. It uses "have you?" as the question tag, which matches the present perfect tense of the main clause ("haven't seen"). (4) "You haven't seen the film, do you?" - This option is incorrect because it uses "do you?" which is incorrect for a question tag following a negative statement in the present perfect tense. The correct question tag for the present perfect tense is "have you?" not "do you?" Therefore, option (3) "You haven't seen the film, have you?" is the correct sentence.
