The correct answer is: Parliament.
The residuary powers are the powers to legislate with respect to any matter not enumerated in any of the three lists in the Seventh Schedule of the Constitution of India. The Seventh Schedule lists the subjects on which the Parliament and the State Legislatures have power to make laws. The residuary powers are vested
in the Parliament.The Parliament is empowered to determine finally as to whether or not a particular matter falls in the residuary category. This is because the Parliament is the supreme legislative body in India. It has the power to make laws on any subject, including those that are not enumerated in the Seventh Schedule.
The Lok Sabha and the Rajya Sabha are the two Houses of Parliament. The Lok Sabha is the lower House of Parliament, while the Rajya Sabha is the upper House of Parliament. The Judiciary is the branch of government that is responsible for interpreting the law.
The Lok Sabha and the Rajya Sabha do not
have the power to determine finally as to whether or not a particular matter falls in the residuary category. This is because they are not the supreme legislative bodies in India. The Judiciary also does not have the power to determine finally as to whether or not a particular matter falls in the residuary category. This is because the Judiciary is not responsible for making laws.
