Correct option is D
The correct answer is (d) Government of India Act, 1919.
• The Montagu-Chelmsford Reforms, introduced by Edwin Montagu, the Secretary of State for India, and Lord Chelmsford, the Viceroy, were implemented through the Government of India Act, 1919.
• These reforms introduced the system of Dyarchy in the provinces, which divided the subjects of provincial governments into two categories: transferred and reserved.
• The transferred subjects were administered by Indian ministers responsible to the legislative councils, while the reserved subjects remained under the control of the Governor and his executive council.
• Dyarchy aimed to gradually introduce self-governing institutions in India and prepare Indians for greater self-governance.
