Ancient History question: Which one port-related Harappan sites are known from the western coast?

The verified response to “Ancient History question: Which one port-related Harappan sites are known from the western coast?” is Lothal and Sutkagendor, option B. The original question-specific evidence states: Lothal and Sutkagendor are associated with maritime trade and coastal contact. Lothal and Sutkagendor is the correct answer to “Which one port-related Harappan sites are known from the western coast”. 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 Harappa and Ropar, Manda and Alamgirpur and Kalibangan and Banawali do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. The attribution is presented as an exam-oriented historical identification and should be read within the archaeological context stated in the question. Then compare the chosen answer with the relevant NCERT theme and reject options belonging to another site or category. Replaying that method confirms Lothal and Sutkagendor 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.
