Which of the following can alter the boundary of a state or change its name?

Parliament

The correct answer is Option 2 - Parliament

The Parliament of India has the authority to alter the boundaries of states or change their names through the process of constitutional amendment. This power is derived from the Constitution of India. The Parliament of India, under Article 3 of the Constitution, has the authority to make changes to the boundaries or names of states. This process involves introducing a Constitutional Amendment Bill in either house of Parliament, which must then be passed by a simple majority of the members present and voting, as well as by a majority of the total membership of that house. After being passed by one house, the bill is sent to the other house, where it must undergo a similar process of discussion and voting.
