Option a is the correct answer. Kulottunga Chola (also spelt Kulothunga; r. 1070 - 1122 CE) was an 11th-century monarch of the Chola Empire. He sent 72 traders to China. He was one of the sovereigns who bore the title Kulottunga, literally meaning the exalter of his race. He did not belong to the main line of Cholas but was rather a prince of the Eastern Chalukya dynasty. His mother was a Chola princess and the daughter of emperor Rajendra Chola I. His accession marked the beginning of a new era and ushered in a period of internal peace and benevolent administration.
