Correct answer: B. Krishnadevaraya
Explanation: Krishnadevaraya was the most famous ruler of the Tuluva dynasty of the Vijayanagara Empire. He ruled in the early sixteenth century and is remembered for strong administration, military success, support for literature, and encouragement of art and temple building. Thus, the question is asking us to connect the Tuluva dynasty with its best-known ruler, not merely with any ruler of Vijayanagara.
Among the choices, Devaraya II belonged to the Sangama dynasty, while Harihara I was an early founder of the empire and also belonged to the Sangama line. Rama Raya was an important later political figure, but he was not the famous Tuluva ruler sought here. Therefore, option B, Krishnadevaraya, is correct.
