The correct answer is option 'B', which states that the Government of India Act of 1919 clearly defined the jurisdiction of the central and provincial governments.

Explanation:

The Government of India Act of 1919, also known as the Montagu-Chelmsford Reforms, was an important constitutional development in India during the British colonial rule. It was enacted to introduce some reforms in the governance of India and to address the demands for increased participation of Indians in the administration.

The act consisted of several provisions that aimed to redefine the relationship between the central government and the provincial governments. It introduced a system of dyarchy, which divided the powers and responsibilities between the British government and the Indian government.

Under the Government of India Act of 1919, the jurisdiction of the central and provincial governments was clearly defined. The act divided the legislative powers of the central government into two categories: reserved subjects and transferred subjects.

Reserved subjects were under the exclusive control of the central government and included matters such as defense, foreign affairs, and taxation. On the other hand, transferred subjects were under the control of the provincial governments and included matters such as education, health, and agriculture.

This division of powers clearly defined the areas of jurisdiction for both the central and provincial governments. It aimed to provide greater autonomy to the provinces and allow them to have more control over their own affairs.

The act also established separate executive and legislative functions for both the central and provincial governments. It introduced the concept of dual government, where certain matters were administered by the central government, while others were administered by the provincial governments.

In conclusion, the Government of India Act of 1919 clearly defined the jurisdiction of the central and provincial governments. It divided the legislative powers and responsibilities between the two levels of government, establishing a system of dyarchy. This act was an important step towards increasing Indian participation in the governance of their own country.
