The correct answer is "Missouri was a slave state and would upset the balance between free and slave states."

Missouri’s request to join the Union increased sectionalism in that "Missouri was a slave state and would upset the balance between free and slave states."

Congress had to make a decision between sectionalism and permanent confrontations between slave and non-slave states. So the US Congress decided to accept Missouri as a slave state in 1840 but also accepted the state of Maine as a non-slave state to maintain the balance in Congress. This decision was better known as the "Missouri Compromise."

The correct answer is A. Missouri's request to join the Union increased sectionalism because it was a slave state and would upset the balance between free and slave states.

The admission of the new slave state of Missouri would unbalance the composition of the Senate (each state had and has two representatives, regardless of its population), in favor of the slave states.

The solution that was reached consisted of admitting the state of Missouri, at the same time as the state of Maine, (which depended on the state of Massachusetts), as a non-slave state.
