The correct answer is C) Crittenden Compromise.
The Crittenden Compromise was the last attempt at compromise before Southern secession.
In the difficult times before the beginning of the American Civil War, some Congressmen made a las effort to pass some legislation that prevented the imminent armed conflict between the northern states and the southern states. It was John Crittenden, Kentucky Senator, who in the last days of 1867 proposed the Crittenden Compromise. However, although it had some support in the South, President Abraham Lincoln did not like the idea and many northern states did not support the compromise.
