Which among the following viceroy’s period the title of ‘Rai Bahadur’ and ‘Khan Bahadur’ began to confer to Indian?

Explanation

To win the confidence of the princely rulers, zamindars, etc. who helped the British during the Revolt of 1857, the British began granting them facilities such as titles, robes of honour (khil'at), land grants, loan waivers, etc. Among these, the major title given to Hindus was ‘Rai Bahadur’, and the equivalent title given to Muslims and Parsis was ‘Khan Bahadur’. Evidence of these titles being conferred is found from 1859–1860 A.D. onwards.
