This question was previously asked in
UPSC CAPF – 2013
The correct answer is C. The prevalence of various types of grain (wheat, barley, rice, millet, pulses, etc.) found at numerous Harappan sites is direct evidence that agriculture was a major economic activity in the Harappan civilization.
– Archaeological excavations at Harappan sites have unearthed large quantities of domesticated plant remains, primarily grains.
– Granaries have been found at major sites like Mohenjo-Daro and Harappa, suggesting surplus production and storage of grains.
– Evidence like terracotta plough models and ploughed fields at Kalibangan further supports the practice of agriculture.
While options A and B relate to agricultural practices (ploughing, broadcasting seeds), the mere *prevalence* of grain directly confirms that agriculture itself was widespread (C). While trade in grains likely occurred (D), the abundance of grains at sites points to local production as the primary reason for their prevalence, making agriculture a key feature of the economy.
