The correct option is A Amoghavarsha
The early reign of Amoghavarsha had to face many obstacles. But he was not interested in feuds and desired peace. Hence he got rid of the enmity by developing marital relations with the Gangas and the Pallavas. Since he was a peace-loving king, he had to give up some territories in the north. The ports of the west coast were busy trading centers and enjoyed great prosperity by developing trade relations with Persia and Arabian. Many travelers and merchants visited the kingdom during this period. Prominent among them was the Arab travaler Sulaiman. He has praised Amoghavarsha as one of the four powerful emperors of the World.
