During which Gupta King's reign did the Chinese traveller Fahien visit India?

Answer: Option C

Fa-hien, a Chinese pilgrim, visited India during the reign of Chandra Gupta II. His primary aim was to visit the Buddhist religious places and to take with him the copies of the Buddhist religious texts. He, therefore, travelled through the Gupta empire and also wrote down his impressions about India. As his main interest was religion, we know nothing about the political condition of India from his account.
