Asked by GIANSH GUPTA KHUNDKER · BIRLA BRAINIACS
Answer: B. have we seen
Answer: B) have we seen
Explanation: Starting a sentence with a restrictive adverb like Seldom forces subject-verb inversion. The auxiliary verb (have) must move before the subject (we). Option C is incorrect because the auxiliary did must be followed by a base verb (see), not a past tense verb (saw).
