The correct answer is letter D
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 Federalism, the division of power occurs through delegation, that is, the central political power is shared by each of the federative units.
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.
