Which best states how a section of the Missouri Compromise supported Dred Scott's argument?

The Missouri Compromise declared that an enslaved person gained his or her freedom upon entering a free state. In the famous Dred Scott Supreme Court case, Dred Scott was a slave who was brought into a free territory by his owner. After living there for an extended period of time and after his master passed away, Scott sued for his freedom. His argument relied on the fact that he was in a free territory and that this legally made him a free man. However, the Supreme Court justices ruled that slaves are not people. Rather, they are property and have no right to sue in court. This ruling essentially made slavery legal everywhere, delivering a huge blow to the abolitionist movement of the time.I hope this helps love <3 (:
