The original question-specific evidence states: Manda in the Jammu region marks the northern extension of the Harappan Civilization. Manda is the correct answer to “Which site marks the northern limit of the Harappan Civilization”. 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 Alamgirpur, Sutkagendor and Daimabad do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. A reliable check begins by identifying the question type: location, site feature, archaeological find, economic activity, urban planning, chronology or interpretation. Then compare the chosen answer with the relevant NCERT theme and reject options belonging to another site or category. Replaying that method confirms Manda as the keyed response for this Ancient History question.
