The options of the answer are:
A) address slavery in the Northern states.
B) maintain the balance of power in Congress.
C) fully resolve the concerns about slavery.
D) address how new states would enter the Union.
The correct answer is C) fully resolve the concerns about slavery.
<em>Thomas Jefferson was concerned about the Missouri Compromise because it did not fully resolve the concerns about slavery.
</em>
When Congress passed the Missouri Compromise, it represented an option to keep a balance between the states with slavery and the states which did not have it. The Missouri Compromise considered Maine as a free state but considered Missouri as a slave state. Thomas Jefferson was concerned about the Missouri Compromise because it did not fully resolve the concerns about slavery because it did not propose a firm resolution on slavery. It was considered just a reprieve.
