The Government of India Act of 1919 clearly defined

The Government of India Act of 1919 clearly defined the jurisdiction of the central and provincial governments by demarcating and separating administrative subjects into two distinct lists to relax central control. While option (c) is a common distractor, the Act primarily focused on administrative devolution rather than redefining the constitutional powers between the Secretary of State and the Viceroy. The core concept tested is the introduction of federal principles through the classification of subjects, which laid the groundwork for provincial autonomy.
