The verified response to “Ancient History question: Kalibangan is located in which present-day state/province?” is Rajasthan, option D. The original question-specific evidence states: Rajasthan correctly answers “Kalibangan is located in which present-day state/province”. The Ancient History location or historical association asked in “Kalibangan is located in which present-day state/province” is identified by Rajasthan. The choice Rajasthan matches the site, region, country, state, feature, or description required by this question. This evidence connects the required Ancient History fact with its archaeological, geographical, cultural or chronological setting. The choices Haryana, Gujarat and Punjab (Pakistan) do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. Replaying that method confirms Rajasthan 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.
