Which ruler had made Pataliputra the capital of his empire for the first time?

Explanation

In fact, Pataliputra was founded by Udayin, a ruler of the Haryanka dynasty, at the confluence of the Ganga and Son rivers, and he shifted his capital from Rajagriha to Pataliputra. However, since Udayin is not given in the options, Chandragupta Maurya is the correct answer.
