Correct Answer: Parliament

Solution : The correct option is Parliament .

The Indian Parliament is involved in the process of admitting a new state to the Union of India. A resolution is introduced, debated, and voted on in both the Lok Sabha and the Rajya Sabha of Parliament. If the resolution is adopted by a majority in both chambers, it gains the president's formal assent, resulting in the establishment and admission of the new state to the Union. This procedure assures that the decision to admit a new state is both constitutional and legislative, necessitating national approval.
