Correct Answer: (d) 1991
Solution:The Government of National Capital Territory of Delhi (Amendment) Bill, 2021, which was passed in March 2021, amended the Government of National Capital Territory of Delhi Act, 1991. The bill sought to amend various provisions of the Act, including those related to the powers of the Lieutenant Governor and the Delhi Legislative Assembly. The Act provides a framework for the functioning of the government in the National Capital Territory of Delhi, which includes the capital city of New Delhi. The amendment has been a subject of controversy, with some critics arguing that it undermines the authority of the elected government of Delhi.
