The correct option is C extend Provincial Assemblies
Morley-Minto Reforms of 1909 was primarily aimed at extending Provincial Assemblies. The number of elected members in the Imperial Legislative Council and Provincial Legislative Councils was increased. In the Provincial Councils, the non-official majority was introduced, but since some of these non-officials were nominated and not elected, the overall non-official majority remained. The elected members were also not directly elected, they were to be indirectly elected.
