In the Harappan civilization, several large cisterns and reservoirs have been found in the citadel and lower-town areas of the city of Dholavira. The Harappan civilization was known for its advanced urban planning and water management systems, and Dholavira is one of the most remarkable examples of this.

Dholavira is located in modern-day Gujarat, India and was one of the largest cities of the Harappan civilization. The city was built on a hill and was divided into three sections - the citadel, the middle town, and the lower town. The citadel was the highest and most fortified area of the city, whereas the lower town was situated on the lower slopes of the hill.

The large cisterns and reservoirs found in Dholavira indicate that the city had a sophisticated water supply and storage system. These structures were likely used to collect, store, and distribute water throughout the city, ensuring a reliable water supply for the inhabitants.

Therefore, option 3 - Dholavira is the correct answer as it is the Harappan city where several large cisterns and reservoirs have been found in the citadel and lower-town areas.
