Which one of the following ancient towns is well-known for its elaborate system of water harvesting and management by building a series of dams and channelizing water into connected reservoirs?

Dholavira is the correct answer because it features a sophisticated network of stone-cut reservoirs and dams designed to harness water from the ephemeral Mansar and Manhar streams in the arid Rann of Kutch. While Kalibangan is a significant site known for its unique ploughed fields and fire altars, it lacks the specialized hydraulic engineering and interconnected reservoir system found at Dholavira. This question tests the core concept of site-specific urban planning and advanced civil engineering capabilities within the Indus Valley Civilization.
