The correct answer is D. Missouri
Explanation:
In U.S. history, during 1860 and 1861 different states from the south seceded from the U.S. which means they separated from the U.S. or Union and aimed at creating a new nation forming the Confederate States of America, which lead to the American Civil War. This included states such as South Carolina that seceded on December of 1860, Louisiana that seceded on January of 1861, Arkansas and North Carolina that ceded on May of 1861 and Tennessee that ceded on June of 1861. In the case of Missouri, this state was located in the border of the Union that were the states that were loyal to the U.S. and the Confederates and in this state there was an ordinance of secession in 1861, but the state never seceded due to the opposition of those that supported the Union and therefore this state remained as part of the Union. Thus, all states (North Carolina, Arkansas, and Tennesse) seceded except Missouri.
