b. the missouri compromise drew a dividing line between slave states and free states.
c. the missouri compromise declared that when a slave state entered the union, a free state must enter as well.
d. the missouri compromise determined the number of free and slave states in the union.

The correct answer is A) 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.
