The Anantraj Sagar Tank was built by the ____ rulers.

Vijayanagara

The correct answer is Option 1- Vijayanagara

 The Anantraj Sagar Tank was built by the Vijayanagara rulers.

The Vijayanagara Empire was a Hindu empire that ruled over much of southern India from the 14th to the 16th centuries. The empire was founded by Harihara I and Bukka Raya I in 1336 AD, and it reached its peak under the rule of Krishnadevaraya in the early 16th century.

The Vijayanagara rulers were great patrons of the arts and sciences. They built many temples, forts, and other public works projects. The Anantraj Sagar Tank is one of the most impressive examples of Vijayanagara engineering. It is a large reservoir with a capacity of over 100 million cubic meters of water. The tank was used to irrigate the surrounding farmland and to provide drinking water for the people of the region.

The Vijayanagara Empire was eventually defeated by the combined forces of the Deccan sultanates in 1565 AD. However, the legacy of the Vijayanagara Empire continues to this day. The Anantraj Sagar Tank is still in use today, and it is a testament to the engineering skills of the Vijayanagara people.
