Pinpoint Error Detection

Which of these is correct?

Option D is correct because all the other options contain grammatical errors. Option A and C are missing an article before 'director' and 'film' respectively, and option C misspells 'film' as 'flim'. Option B is grammatically correct but is awkwardly phrased; a more natural way to ask the question would be 'Who is the director of the film?'
