The correct answer is C) Dholavira.
Dholavira, located in Kutch, Gujarat, is renowned among Harappan sites for its sophisticated water harvesting system. Archaeological excavations have revealed numerous large reservoirs and cisterns carved into the ground, designed to collect and store rainwater during the monsoon season. These water storage facilities are found across the site, including within the fortified citadel and the lower town, highlighting the importance placed on water management in this arid region.
While other Harappan cities like Mohenjodaro have important water-related structures (e.g., the Great Bath, wells, drains), Dholavira stands out for its extensive network and large number of reservoirs dedicated to water storage, reflecting unique adaptations to the local environmental conditions. Banawali is noted for its semi-arid location and lack of a clear grid pattern in the lower town. Rakhigarhi is one of the largest Harappan sites but is not particularly known for large cisterns and reservoirs on the scale found at Dholavira.
