Answer:
4. A legal division of authority between the national, state, and local governments
Explanation:
Federalism is a form of organization of the State in which there is a government that exercises the functions of a centralizing State. But at the same time that there is a central power, there is a division of power between the units that form it. These units, when they are united and regulated by a common Federal Constitution, form a Federal State. In practice, this form of organization means that there are different poles of administration that are divided within a country. Power is distributed among the territories that form the state.
