Explanation
Why Correct: Rajaraja Chola I (r. 985–1014 CE) bore the pre-coronation name Arumolivarman, meaning 'the virtuous one who wears the garland of virtues'.
Distractor Analysis: Vira Rajendra was the son of Rajendra I and ruled 1063–1070 CE. Rajendra Chola I was Rajaraja's son, known as Madhurantaka before coronation. Kulottunga Chola I was a Eastern Chalukya prince who merged the Chola throne, originally called Rajendra.
Takeaway: Rajaraja Chola I built the Brihadeeswarar Temple at Thanjavur, completed in 1010 CE, and introduced the land survey system for revenue administration.
