The correct answer is (a) Chandragupta II.
Hiuen-Tsang was a Chinese Buddhist monk who traveled to India in the 7th century CE. He visited the Gupta Empire during the reign of Chandragupta II, who was also known as Vikramaditya. Hiuen-Tsang wrote extensively about his travels in India, and his accounts provide valuable information about the history and culture of the Gupta period.
Chandragupta II was the grandson of Samudragupta, the founder of the Gupta Empire. He ascended to the throne in 375 CE and ruled for over 40 years. During his reign, the Gupta Empire reached its zenith of power and prosperity. Chandragupta II was a great patron of the arts and sciences, and he is credited with reviving the Gupta Renaissance.
Hiuen-Tsang arrived in India in 630 CE. He spent the next six years traveling throughout the country, visiting major cities such as Pataliputra, Nalanda, and Ayodhya. He also met with many of the leading scholars and religious figures of the time.
Hiuen-Tsang’s accounts of his travels are an invaluable source of information about the Gupta period. They provide details about the history, culture, religion, and society of India at that time. They also contain valuable information about the Gupta Empire itself, including its political structure, economy, and military.
Hiuen-Tsang’s accounts were translated into Chinese and published in the 7th century. They were later translated into other languages, including English. They have been widely read and studied by historians and scholars of Indian history.
The other options are incorrect because they were not rulers of the Gupta Empire during the time that Hiuen-Tsang visited India.
