The verified response to “Ancient History question: Which motif appears most frequently on Harappan seals?” is Unicorn bull, option C. The original question-specific evidence states: The unicorn bull is the most common motif on Harappan seals. Unicorn bull is the correct answer to “Which motif appears most frequently on Harappan seals”. 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 Horse, Camel and Tiger do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. Replaying that method confirms Unicorn bull as the keyed response for this Ancient History question.
