Importantly, the Preamble declares who is enacting this Constitution—the people of “the United States.” The document is the collective enactment of all U.S. citizens. The Constitution is “owned” (so to speak) by the people, not by the government or any branch thereof.
The answer that is not true is A: "Scott could only sue in state courts."
Whether Dred Scott, as a slave, had any legal right to sue in court was a matter that applied whether talking about state or federal courts. When Scott's suit was rejected by a state of Missouri court, Scott and his supporters managed to bring the case into a federal court, and it went all the way to the Supreme Court. Though the Supreme Court at the time ruled that Scott had no right to bring the suit because he was a slave and not a citizen (point D above), the case gave Chief Justice Roger Taney opportunity to make further statements regarding the slavery issue, including points B and C in your list above.
I think that the purpose of the U.S. Government is to first of all serve as leadership for the entire U.S. and to make sure that all things are done in order and decency and to set up laws that will keep American society under control. Hope this helps and mark as brainliest if right, please?!
