Fa-hien (Faxian) visited India during the reign of Chandragupta II (c. 375–415 CE) to collect authentic Buddhist scriptures and visit holy sites associated with the Buddha. While Samudragupta (Option A) was a major Gupta emperor, his reign ended before Fa-hien’s arrival, and students often confuse Fa-hien with the later pilgrim Hiuen Tsang, who visited during the reign of Harshavardhana. The core concept being tested is the chronological association between significant foreign travelers and the contemporary Indian dynasties they documented.
