Option a is the correct answer. Kulottunga I was the Chola king who gave complete freedom to Sri Lanka and got his daughter married to the Sinhala prince. He ruled from 1070 to 1122 CE and was one of the sovereigns who bore the title Kulottunga, 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.
