Correct Answer: (a) 1st Amendment
Solution:The First Amendment was passed in 1951 by the Provisional Parliament, members of which had just finished drafting the Constitution as part of the Constituent Assembly. The First Amendment Act amended Articles 15, 19, 85, 87, 174, 176, 341, 342, 372 and 376. In Article 15, Clause 4 was added to make special provisions for the backward classes or for the Scheduled Castes and Scheduled Tribes. Certain restrictions were added in Article 19 by including the terms 'public order', 'friendly relations with foreign states, and 'incitement to an offence'. This amendment also added the Ninth Schedule to protect the land reforms and other laws included in it from the judicial review by adding Articles 31A and 31B. A number of rulings by the Supreme Court and High Court that declared certain sections of criminal legislation, regulations pertaining to the press, and public safety to be incompatible with the constitutional right to free expression served as the immediate impetus for the modifications.
