Answer:
The correct answer is D. Interdependency in Federalism generally means that the States and the National Government work together to accomplish a common goal.
Explanation:
Interdependence implies a situation in which several factors work together to achieve a common goal, and in turn depend on each other to achieve those goals.
Regarding the political organization of the United States, the federalist system implies the existence of a federal government and, in turn, state governments of each of the states that make up the Union.
There is an interdependence between the federal government and the state governments, since these entities work together with the objective of improving the lives of their citizens, while seeking the common objective of enforcing the laws, managing resources and ensuring the justice in the territories in which they have competence.
