The Permanent Zamindari Settlement was a land revenue system introduced by Lord Cornwallis in 1793 in Bengal and later extended to other parts of British India. Under this system, the zamindars were made permanent owners of the land and were responsible for paying a fixed amount of revenue to the British government. The system was meant to provide stability to the revenue collection process and encourage investment in agriculture.

Explanation:

The correct answer to the question is option 'D' - Bombay Presidency. The Permanent Zamindari Settlement was not extended to the Bombay Presidency, which included present-day Maharashtra, Gujarat, and parts of Karnataka.

Reasons for not extending the Permanent Zamindari Settlement to Bombay Presidency:

1. Different land tenure system: The Bombay Presidency had a different land tenure system than the ones in Bengal, Bihar, and Orissa. The land was mainly held by peasant proprietors, and there were few large landholders like zamindars. Therefore, the Permanent Zamindari Settlement was not relevant to the region.

2. Political instability: The Bombay Presidency was marked by political instability during the late 18th and early 19th centuries. The Maratha Empire, which had controlled the region, was in decline, and there were frequent wars and revolts. The British government was not able to establish a stable administration in the region, which would have been necessary for implementing the Permanent Zamindari Settlement.

3. Revenue collection through other methods: The British government adopted other methods of revenue collection in the Bombay Presidency. The land revenue was collected directly from the peasant proprietors, and the government introduced other taxes like the salt tax, excise duty, and customs duty.

In conclusion, the Permanent Zamindari Settlement was not extended to the Bombay Presidency due to the region's different land tenure system, political instability, and the adoption of other revenue collection methods.
