The Nalanda Mahavihara in Bihar was founded by which Gupta ruler?

The correct answer is C, Kumaragupta I. Kumaragupta I, who took the title Mahendraditya, founded the monastery and seat of learning at Nalanda in the fifth century CE. Later Gupta rulers, Harsha of Kanauj and the Pala kings endowed it further, and the Chinese pilgrim Hiuen Tsang, who studied there in the seventh century, describes its monasteries, library and thousands of monks. It was sacked in the late twelfth century.

Option A, Chandragupta I, began the Gupta era of 319 to 320 CE and married the Lichchhavi princess Kumaradevi, but no university is credited to him. Option B, Samudragupta, is remembered for the conquests of the Prayag Prashasti and for his veena coins. Option D, Skandagupta, is remembered for repelling the Hunas and for repairing the Sudarshana lake, recorded in the Junagadh inscription. Nalanda belongs to Kumaragupta I.
