Who statement is true with regard to the results of the Missouri Compromise?

The Missouri Compromise, enacted in 1820, was significant in maintaining the balance between free and slave states in the U.S. It allowed Missouri to enter the Union as a slave state while Maine entered as a free state, thus preserving the balance in Congress. Additionally, it established a line (the 36°30′ parallel) north of which slavery was prohibited in the Louisiana Territory, highlighting the growing sectional divides over slavery. Ultimately, the compromise was a temporary solution that foreshadowed further conflict leading to the Civil War.
