Who among the following medieval travellers' became a 'sanyasi' for sometime in India?

Mahmud Wali Balkhi

The correct answer is Option (2) → Mahmud Wali Balkhi

Mahmud Balkhi even became a sort of sanyasi for a time during his travels in India.

Among the best known of these writers were Abdur Razzaq Samarqandi, who visited south India in the 1440s, Mahmud Wali Balkhi, who travelled very widely in the 1620s, and Shaikh Ali Hazin, who came to north India in the 1740s. Some of these authors were fascinated by India, and one of them – Mahmud Balkhi – even became a sort of sanyasi for a time. Others such as Hazin were disappointed and even disgusted with India, where they expected to receive a red carpet treatment. Most of them saw India as a land of wonders.
