The Right to Information Act, 2005 (RTI Act) fully came into force on October 12, 2005. It repealed and replaced the earlier Freedom of Information Act, 2002. The RTI Act is considered to be an operationalization of the fundamental right to freedom of speech and expression under Article 19(1)(a) of the Constitution, particularly the right to know. Therefore, statement (4) is generally considered incorrect as the Act facilitates this fundamental right. Statement (2) is incorrect; the RTI Act overrides the Official Secrets Act, 1923 in case of conflict, but it did not repeal the entire Act. However, option C is the only one including both correct statements (1) and (3), alongside the debatable statement (4). This suggests the question or options may have an issue, but based on common exam patterns, option C is the most probable intended answer if statements (1), (3), and (4) are considered correct in the context of the question's source.
