Which of the following is not a characteristic of confederation?

The characteristic that is not associated with confederation is: "Sovereignty resides in the centre." In a confederation, sovereignty is vested in the constituent units (states, provinces, or territories), and not in the central government. The central government has limited powers, and the constituent units have more autonomy in decision-making. The other characteristics of a confederation include the right to secede, autonomous units that are more powerful than the centre, and decisions are taken through an agreement between the centre and the constituent units.
