what was a provision of the missouri compromise?
○ missouri was admitted to the union as a free state.
○ maine was admitted to the union as a free state.
○ louisiana was admitted to the union as a slave state.
○ illinois was admitted to the union as a slave state.

Explanation:

The Missouri Compromise (1820) aimed to balance free and slave states in the U.S. It admitted Missouri as a slave state, and Maine as a free state to preserve the Senate balance. It also banned slavery in new territories north of the 36°30' parallel (except Missouri). The other options are incorrect: Missouri was a slave state, Louisiana was admitted before the compromise, and Illinois was a free state.

Answer:

B. Maine was admitted to the union as a free state.
