The correct answer is “A simple majority in Parliament”.
According to Article 3 of the Indian Constitution, a Bill for the purpose of creating a new State in India must be passed by a simple majority in both Houses of Parliament.
This means that the bill requires a majority of the members present and voting in both Houses of Parliament (Lok Sabha and Rajya Sabha) but does not require ratification by the states. Additionally, the President must refer the bill to the concerned state legislature for its opinion, though this opinion is not binding.
