The verified response to “Ancient History question: Evidence of a ploughed field has been found at:” is Kalibangan, option C. The original question-specific evidence states: Kalibangan yielded evidence of a ploughed agricultural field. Kalibangan is the correct answer to “Evidence of a ploughed field has been found at:”. This evidence connects the required Ancient History fact with its archaeological, geographical, cultural or chronological setting. Harappan evidence must be interpreted from excavated settlements, artefacts, environmental data and comparisons among sites; a single object should not automatically support a wider claim than the evidence permits. The choices Manda, Ropar and Lothal do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. Replaying that method confirms Kalibangan as the keyed response for this Ancient History question. This evidence-led approach strengthens factual recall, chronological caution and option elimination for SSC, Railway, Banking, Defence, State and other competitive examinations.
