Who among the following was regarded as the "establisher of the Yavana kingdom".

Krishna Dev Raya

The correct answer is Option (3) → Krishna Dev Raya

The raid and plunder of Vijayanagara towns and villages by the Deccan sultans came to an end during the Raya's rule. In 1509, Krishnadevaraya's armies clashed with them and Sultan Mahmud was severely injured and defeated. Yusuf Adil Shah was killed and the Raichur Doab was annexed. Taking advantage of the victory, the Raya reunited Bidar, Gulbarga, and Bijapur into Vijayanagara and earned the title "establisher of the Yavana kingdom" when he released Sultan Mahmud and made him de facto ruler. The Sultan of Golconda Sultan Quli Qutb Shah was defeated by Timmarusu, the prime minister of Krishnadevaraya. 

So, the correct option is [3].
