Answer:
Whether the South had the right to secede.
Step-by-step explanation:
In the history of America, the issue of slavery and the election of Abraham Lincoln became the primary issues of the states' decision to secede from the Union. This was because while the South states wanted to continue with their 'possession' of slaves, the presidency of Lincoln believes in abolishing this very practice of racial discrimination.
Jefferson Davis and Abraham Lincoln both wanted to avoid any war that will have a huge fallout on the people of the United States. But at the same time, the two leaders strongly disagree on the issue of whether the South had the right to secede.
Thus, the correct answer is the second option.
