The correct option is C Nicolo Conti
In the year 1420 or 1421 A.D. during the Vijayanagara Empire, Nicolo Conti, an European visitor visited India during the reign of Deva Raya II. It was during this time that the explorer Nicolo Conti and Persian chronicler Abdur Razzak arrived in South India. His visit must have taken place shortly after the accession of Deva Raya II.
