Key Points:
• The Government of India Act 1919 (often colloquially termed the Indian Council / Constitutional Reforms Act of 1919):
• Montagu-Chelmsford Reforms (Mont-Ford): Named after Edwin Montagu (Secretary of State) and Lord Chelmsford (Viceroy).
• Rectification of 1909 Defects: Addressed the fundamental shortcomings of the Morley-Minto Reforms (1909), which had provided representation without real power or legislative responsibility.
• Foundation of Responsible Government: Introduced the concept of gradual development of self-governing institutions and implemented Dyarchy (dual rule) in the provinces (dividing subjects into 'Transferred' and 'Reserved').
• Statement (d) is false because Morley-Minto refers strictly to the 1909 Act.
• The Act also introduced bicameralism and direct elections at the Central level.
• Key Takeaway: The 1919 Act is the Mont-Ford Act, rectified 1909 flaws, and laid responsible governance foundations (Morley-Minto is 1909).
