This question asks which PAIR is NOT correctly matched (i.e., identify the WRONG pairing). Bharatnatyam-Tamil Nadu (A) is correct. Kuchipudi-Andhra Pradesh (C) is correct. Bhangra-Punjab (D) is correct. However, Mohiniattam-Orissa (B) is INCORRECT because Mohiniattam is the classical dance of KERALA, not Orissa (Odisha's classical dance is Odissi). Since the question asks for the incorrectly matched pair, option B is the right answer to the question.
