One of the important features of the Constitution of the United States is that:

A. Congress can levy taxes but it cannot collect them

B. it cannot be amended

C. it divides power between the federal and the state governments

D. it is a revision of the Articles of Confederation

So B is definitely not correct. A is not super important. Gotta wither be C or D but it is probably C because that is why they did revisions to the AoC because they needed a new system.

Answer: C

C. it divides power between the federal and the state governments

Explanation:

The Federal Government of the United States is the national state of the United States, a constitutional republic of North America, composed of 50 states, a federal district, Washington D. C. (the national capital) and several territories. It is constituted under the theories of separation of powers, checks and balances. The federal state is divided into three separate, divided and separate branches: legislative, executive and judicial, whose powers are conferred by the Constitution of the United States in Congress, the president and the federal courts, respectively. Each branch has an exclusive sphere of its own competence and powers that allow them to limit the actions of the other two branches. The purpose of this system is to avoid the tyranny that would occur if one branch of public power concentrated too much power and dominated the other two. The powers and duties of these branches are defined in more detail by the minutes of the Congress, including the creation of executive departments and courts inferior to the Supreme Court.
