Answer:
All courts, except the US Supreme Court, established by Congress.
The Supreme Court was established under the article III of the Constitution, however, Congress was granted the authority to create lower federal courts whenever they are required. The Judiciary Act of 1789 established structure and jurisdiction of the federal court system.
The United States has a dual court system, since it has both a federal judiciary and state judiciaries. State courts are established by each state, and these vary from state to state
It's between A and B. The articles of confederation made the federal government weak and pretty much non-existent in terms of true power. Effectively each state was its own country more or less.
I think A and B sound pretty identical though perhaps choice A isn't the best answer because each state didn't really think about the country as a whole, but rather focused on their own backyard.
<h3>So that's why I'm thinking the final answer is choice B</h3>
Though I would get a second opinion on the matter.
