The correct answer is Rajaraja I.
During the reign of Rajaraja I (985-1014 AD), the Sailendra ruler of Sri Vijaya, Mara Vijayatunggavarman, built a Buddhist monastery (Vihara) named Chudamani Vihara at Negapatnam (Nagapattinam) in Tamil Nadu. Rajaraja I patronized this initiative by granting the village of Anaimangalam for the maintenance of the Vihara.
This act reflects the cordial relations between the Chola and Sailendra kingdoms during this period, despite later conflicts involving Rajendra I and Sri Vijaya.
