Which district is known as the 'Silk City of Bihar'?

nd is known as the Silk City of Bihar. The key to this question is the precise association expressed in its wording: “Which district is known as the 'Silk City of Bihar'?” The answer Bhagalpur matches that clue directly and is therefore factually appropriate. Option A — Muzaffarpur — 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 — Darbhanga — is incorrect because it does not match the exact person, district, location, institution, river, event or identifying feature required by the question. Option D — Purnia — 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.
