Yes, I am confident in that answer. Abraham Lincoln’s plan for Reconstruction, often referred to as the "10 Percent Plan," aimed to reintegrate the Southern states into the Union as quickly and smoothly as possible after the Civil War. His goal was to restore the Union while fostering reconciliation rather than punishment, which is why option A is the best choice.
It is important to note that Lincoln's approach emphasized leniency and encouraged Southern states to form new governments once a certain percentage of their voters took an oath of allegiance to the Union. This contrasts with more punitive approaches that were proposed later by Congress after Lincoln's assassination.
