Option d is the correct answer. Samudragupta was the second emperor of the Gupta dynasty and is known as one of India's best rulers. His brilliant leadership and valiant victories earned him the title of 'Napoleon of India'. He was a great conqueror who carried his sword throughout the length and breadth of India and built the mighty Gupta Empire. He annexed a large number of kingdoms in Aryavarta to the Gupta Empire and defeated at least twelve kings of South India. He was also a great patron of art, a skilled musician, and a generous ruler who maintained peace and amity among his people. He issued seven different types of coins that reflected his achievements and personality. He performed the Ashvamedha sacrifice to assert his sovereignty and power. He was compared to Napoleon by the British historian V.A. Smith, who admired his military prowess and expansionist policy. However, unlike Napoleon, Samudragupta was not power-hungry and never faced defeat or exile.
