In Vijayanagara, water from which one of the following structures was con ducted through the channel to the ”royal centre”

The correct option is Kamalapuram tank.

Step-by-step Explanation:

1. Context of Vijayanagara Water Works:
Vijayanagara is located in the natural basin formed by the river Tungabhadra, which flows in a north-easterly direction. Because this region is one of the most arid zones of the peninsula, elaborate arrangements had to be made to store rainwater and conduct it to the city, especially the imperial core.

2. The Kamalapuram Tank:
The Kamalapuram tank is one of the most prominent water reservoirs built during the early years of the Vijayanagara Empire. It was constructed to collect rainwater and surface runoff.

3. Connecting to the Royal Centre:
Water from the Kamalapuram tank was not only used to irrigate nearby agricultural fields but was also conducted through a channel/aqueduct system directly into the "royal centre" to fulfill the water requirements of the royal palaces, temples, and associated state buildings.

4. Distinction from other structures:
- The Lotus tank (often called the Lotus Mahal enclosure structure) was a secular pavilion rather than a primary reservoir sourcing water to the channel.
- The Hiriya canal drew water from a dam across the Tungabhadra and irrigated the cultivated valley between the sacred centre and the urban core, but the specific reservoir whose water was channeled directly into the royal centre is the Kamalapuram tank.
