3) The North no longer wanted the state in the Union.
4)People in the state felt the Crittenden Compromise had failed

The correct answer is 1. The state’s leaders believed that Lincoln was hostile to slavery.

Explanation:

During 1861 most of the Southern states in the U.S. decided to secede or separate from the rest of the country with the idea of creating a new country. In the case of South Carolina, this was one of the first states to secede from the Union (Northern states)  and make part of the Confederacy along with other states including Florida, Alabama, Georgia, Lousiana, Texas, and Mississippi. Like other states, the main reason why South Carolina secede was that the leaders of this state were pro-slavery. Indeed South Carolina had the highest percentage of slaves of all states and its economy depended on them, additionally to this in 1860 before states seceded Abraham Lincoln was elected as the president and he did not support slavery and wanted to abolish it, which represent a threat to the economy of the states that depend on slavers. Considering this, it can be concluded South Carolina secede from the Union because the state's leaders believe that Lincoln was hostile to slavery as he wanted to abolish it and this was not positive for a state whose economy relied on slavers.
