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