Which famous freedom fighter from Bihar was popularly called 'Bihar Vibhuti'?

arayan Sinha was popularly known as Bihar Vibhuti. The key to this question is the precise association expressed in its wording: “Which famous freedom fighter from Bihar was popularly called 'Bihar Vibhuti'?” The answer Anugrah Narayan Sinha matches that clue directly and is therefore factually appropriate. Option A — Sri Krishna Sinha — 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 — Rajendra Prasad — is incorrect because it does not match the exact person, district, location, institution, river, event or identifying feature required by the question. Option D — Jayaprakash Narayan — 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.
