Answer:
Option B, U.S. Court of Appeals, is the right answer.
Step-by-step explanation:
In the federal court system of the United States, there are three main levels which are known as the district courts, circuit courts and the U.S. Supreme Court. A case can be filed in the federal district court following the federal statutes, treaties or the Constitution. Once the federal district court has given its jurisdiction in a case it can be challenged to the U.S. Court of Appeals.
