The verified response to “Ancient History question: Desalpur is especially famous for which feature?” is Fortified settlement, option D. The original question-specific evidence states: Desalpur is especially known for fortified settlement. Fortified settlement is the correct answer to “Desalpur is especially famous for which feature”. 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 Easternmost Harappan site, Ploughed field and Granary do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. A distractor may be historically important in another context but still be wrong for the relationship asked here. 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 Fortified settlement 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.
