Ancient History question: In which year was the Harappan Civilization first identified through excavation?

The verified response to “Ancient History question: In which year was the Harappan Civilization first identified through excavation?” is 1921 CE, option D. The original question-specific evidence states: The year 1921 is associated with the excavation of Harappa and the recognition of the civilization. 1921 CE is the correct answer to “In which year was the Harappan Civilization first identified through excavation”. 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 1901 CE, 1935 CE and 1942 CE do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. Replaying that method confirms 1921 CE as the keyed response for this Ancient History question.
