The correctly matched pair is "Lord Auckland - First Afghan War".
Lord Dalhousie was the Governor-General of India from 1848 to 1856, and he is associated with the policies of annexation and the introduction of the Doctrine of Lapse. The Revolt of 1857 occurred during the tenure of Lord Canning, who succeeded Lord Dalhousie.
Lord Canning is not associated with Wood's Despatch of 1854. Wood's Despatch is connected to another Governor-General, Lord Dalhousie.
So, statements (i) and (iii) are not correctly matched.
Hence, option (b) is correct.
