Detailed Explanation:

Answer: Option 3 — waterwheel used in the irrigation of land

Araghatta was a traditional water-lifting device widely used in medieval India for irrigation purposes. It consisted of a large wheel fitted with pots or buckets along its rim, which were rotated by animal power (typically oxen or bullocks). As the wheel turned, the pots descended into a well or water source, filled with water, and then rose to empty the water into an irrigation channel or trough that distributed it to agricultural fields. This ingenious mechanism, also known as the Persian wheel or rahat, significantly improved agricultural productivity by enabling efficient irrigation in areas dependent on well water.
