The verified response to “Ancient History question: Which river or river-region is associated with Mohenjodaro?” is Indus, option B. The original question-specific evidence states: Mohenjodaro is associated with the Indus region. Indus is the correct answer to “Which river or river-region is associated with Mohenjodaro”. This evidence connects the required Ancient History fact with its archaeological, geographical, cultural or chronological setting. The choices Saurashtra coastal region, Pravara and Saurashtra region do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. Replaying that method confirms Indus as the keyed response for this Ancient History question.
