Correct Option (B)
The Government of India Act of 1919, based on the Montagu-Chelmsford Reforms, clearly defined the jurisdiction of the central and provincial governments. It achieved this by classifying subjects into two lists:
- Central List: Comprising subjects of national importance, administered by the central government.
- Provincial List: Comprising subjects of local importance, which were further subdivided into:
- Reserved subjects: Administered by the Governor and his Executive Council, without responsibility to the legislative council (e.g., law and order, finance, land revenue).
- Transferred subjects: Administered by the Governor acting with ministers responsible to the provincial legislative council (e.g., education, health, local self-government).
This division introduced the system of 'dyarchy' in the provinces and aimed to demarcate the functional areas of both levels of government.
Incorrect Options
Option 1: The Act of 1919 did not establish a clear separation of powers between the judiciary and the legislature. The principle of judicial independence and its separation from the executive and legislature evolved at a later stage in India's constitutional development.
Option 3: The Act did not primarily focus on redefining the powers of the Secretary of State for India or the Viceroy. While it introduced changes in the central government structure and expanded the Viceroy's Executive Council, its main objective regarding power distribution was the devolution of authority to the provinces and the introduction of dyarchy, rather than a fundamental redefinition of the top imperial authorities' powers.
