Explanation:

Krishna Deva Raya (Correct): He was the most famous ruler of the Vijayanagara Empire, reigning from 1509 to 1529. Babur, the founder of the Mughal Empire, reigned from 1526 to 1530. Their reigns significantly overlapped, making Krishna Deva Raya a contemporary of Babur. Babur himself mentioned Krishna Deva Raya in his memoirs, "Baburnama," as one of the most powerful rulers in India. Harihara I: He was one of the founders of the Vijayanagara Empire and reigned from 1336 to 1356, long before Babur's time. Bukka I: He was also one of the founders of the Vijayanagara Empire and reigned from 1356 to 1377, succeeding his brother Harihara I, also long before Babur's time. Deva Raya II: He was a prominent ruler of the Vijayanagara Empire, reigning from 1422 to 1446. While a significant ruler, his reign concluded well before Babur's arrival in India.
