The correct answer is (d) 1963.
The Prime Minister’s Office (PMO) was established in 1947, shortly after India gained independence from British rule. It was initially a small office with a staff of just a few people. However, its role and responsibilities grew over time, and in 1963, it was given the status of a department. This meant that it was now a separate entity from the Prime Minister’s Secretariat, which is responsible for providing administrative support to the Prime Minister.
The PMO is headed by the Principal Secretary to the Prime Minister, who is the most senior civil servant in the PMO. The PMO is responsible for a wide range of functions, including providing advice to the Prime Minister on policy matters, coordinating the work of the government, and managing the Prime Minister’s public engagements.
The PMO has played a key role in some of the most important events in India’s history, including the Indo-Pakistani War of 1971 and the economic reforms of the 1990s. It is an important part of the Indian government, and its role is likely to continue to grow in the years to come.
The other options are incorrect because the PMO was not given the status of a department in those years.
