In which system of government are all the component units sovereign?

Explanation

In a Confederal system of government, all the component units (such as states or provinces) are sovereign. This means that the component units retain the majority of the power and authority, while the central government has limited powers that are delegated to it by the component units.

In a federal system, sovereignty is shared between the central government and the component units. Both levels of government have constitutionally guaranteed powers, and neither is fully sovereign over the other. In a monarchical system, sovereignty is typically vested in the monarch or the central government, not in the component units. In a republican system, sovereignty resides with the people and is exercised through elected representatives. The distribution of power can vary, but it does not imply that all component units are sovereign.
