Answer: B. Seldom have we witnessed such an extraordinary musical performance.
Answer: (B) Seldom have we witnessed such an extraordinary musical performance.
Explanation: When a sentence begins with a negative or restrictive adverb like seldom, rarely, hardly, or scarcely, the sentence structure undergoes subject-auxiliary inversion (the auxiliary verb "have" must come before the subject "we"). Option D is incorrect because "did" cannot be paired with a past-tense verb like "witnessed".
