The Constitution limits the jurisdiction of federal courts to prevent them from interfering with state courts.
Answer: Option 3
Explanation:
The legal system in the United States has been divided between Federal Courts and State Courts. The State Courts haven't been given the powers to pass rulings in cases pertaining to national issues. That power is retained by the Federal Courts.
The Federal Courts except for the United States Supreme Court haven't been given the powers to hear and pass rulings on internal matters pertaining to the states.
