Who authored the famous work 'Rashmirathi' and belonged to Bihar?

ar, known as the National Poet, wrote Rashmirathi. The key to this question is the precise association expressed in its wording: “Who authored the famous work 'Rashmirathi' and belonged to Bihar?” The answer Ramdhari Singh Dinkar matches that clue directly and is therefore factually appropriate. Option A — Harivansh Rai Bachchan — is incorrect because it does not match the exact person, district, location, institution, river, event or identifying feature required by the question. It may be associated with another Bihar-related context, but that broader association does not satisfy this specific wording. Option C — Maithili Sharan Gupt — is incorrect because it does not match the exact person, district, location, institution, river, event or identifying feature required by the question. Option D — Nagarjun — is incorrect because it does not match the exact person, district, location, institution, river, event or identifying feature required by the question. Bihar GK questions frequently place neighbouring districts, related historical personalities, nearby rivers or institutions from the same field among the options. The correct method is to identify the central clue, match it with the relevant map location, historical period or official designation, and then eliminate every alternative separately.
