The correct answer is option 4 - Dholavira. Dholavira, an ancient Indus Valley city located in present-day Gujarat, India, was known for its advanced water management system. The city had a sophisticated network of channels, reservoirs, and tanks to efficiently manage and store water.

The water management system in Dholavira was designed to address the water needs of the city`s inhabitants, as well as to deal with potential floods or water shortages. The city had several large and small reservoirs to collect rainwater, which was then used for various purposes such as irrigation, drinking water, and domestic use.

Additionally, Dholavira also had a unique underground water harvesting system called the "water harnessing system." This system involved constructing several series of stone and clay conduits to capture and store water underground. The stored water could then be accessed during the dry season or in case of emergencies.

Overall, Dholavira`s advanced water management system highlights the technological and engineering prowess of the Indus Valley civilization in effectively managing their water resources.
