Chandragupta II

The correct answer is Option 1- Chandragupta II

Aryabhata lived during the reign of Chandragupta II.

Aryabhata (476–550 CE) was an Indian mathematician and astronomer. He is considered to be one of the most important figures in the history of Indian mathematics and astronomy.

Chandragupta II (reigned c. 380–c. 415 CE) was the fourth emperor of the Gupta Empire in ancient India. He was a brilliant military strategist and a skilled diplomat, and he quickly expanded the empire to include much of northern India.

Chandragupta II was also a great patron of the arts and learning. He established schools and libraries, and he supported scholars and artists. Aryabhata was one of the many scholars who flourished at the court of Chandragupta II.

Aryabhata's works include the Aryabhattiya and the Arya-siddhanta. The Aryabhattiya is a treatise on mathematics and astronomy that was written in 499 CE. It is divided into four parts: mathematics, astronomy, spherical trigonometry, and calendars. The Arya-siddhanta is a lost work on astronomy that is believed to have been written by Aryabhata.

Aryabhata's works were highly influential in the development of mathematics and astronomy in India and abroad. He made significant contributions to the understanding of trigonometry, algebra, and calculus. He also developed a number of astronomical models that were more accurate than the models that were used before him.
