The correct answer is D) a system in which states agree to form a national government, but maintain its sovereignty.
<em>A Confederation is a system in which states agree to form a national government but maintain its sovereignty.
</em>
In political terms, a Confederation is considered a union of states but maintaining its own soverignty. The United States formed a Federation in 1789, to unify even more the states, something that other states did not like and mostly the Southern states maintained the concept of Confederation. The Federation was based on the idea of a common government for all the states, meanwhile, in a Confederation, the common element was the autonomy in each of the states.
In a federal system, when there are disputes between states, the federal government do not have the power instead it is the Supreme Court of each state that would be the umpire between the states. They will hold the power in order to come up with a right decision.
