The role of the Governor-General in India, established under British rule, was effectively replaced by the office of the President of India with the adoption of the Indian Constitution. The transition marked India's shift from a British Dominion to a Republic. This significant constitutional change took effect on:
26th January 1950
On this day, the Republic of India was officially proclaimed, and Dr. Rajendra Prasad became the first President of India, thereby ending the role of the Governor-General as the head of state. The Constitution of India, which came into effect on this date, outlined the role of the President and established India as a sovereign republic, superseding the Government of India Act 1935 under which the Governor-General's role was defined.
Among the provided options:
- 15th August 1947: This date marks India's independence from British rule but does not signify the end of the Governor-General's role, as India remained a dominion within the British Commonwealth until 1950.
- 9th August 1948 and 22nd October 1950: These dates hold no specific relevance to the end of the Governor-General's rule in India.
Therefore, the correct answer is 26th January 1950.
