The verified response to “Ancient History question: Harappan seals were probably used for:” is Trade and identification, option D. The original question-specific evidence states: Seals likely functioned in trade, ownership and identification. Trade and identification is the correct answer to “Harappan seals were probably used for:”. 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 Music only, Weapons only and Agriculture only 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. 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 Trade and identification 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.
