Which Bollywood film, known for its groundbreaking use of sound design, featured no songs and explored themes of existentialism and urban alienation?
Correct: C
Khamosh (1985) is the correct answer. Directed by Vidhu Vinod Chopra, it's a neo-noir thriller that was critically acclaimed for its innovative use of sound and lack of musical numbers, unusual for Bollywood at the time. It delved into themes not often explored in mainstream cinema then.
