The correct answer is option 1, Article 368. Article 368 of the Indian Constitution empowers the Indian Parliament to amend the constitution. This article outlines the procedure for amending various provisions of the constitution. It states that an amendment can be initiated by either house of Parliament and must be passed by a special majority, which means it requires the support of at least two-thirds of the members present and voting. Additionally, if the amendment seeks to make changes to certain specified provisions like the federal structure, the independence of the judiciary, or the distribution of powers between the center and the states, it must also be ratified by at least half of the states. It is through Article 368 that the Indian Parliament can modify and adapt the constitution to the changing needs and circumstances of the country.
