The correct answer is C) The Presidential plans were more conciliatory and aimed to reestablish the Union quickly.
The primary difference between Presidential and Congressional Reconstruction plans was that the Presidential plans were more conciliatory and aimed to reestablish the Union quickly.
The goal of President Abraham Lincoln was to have a quick unification of the country. He did not complicate the process for the Confederated States to be part of the Union. This decision did not like many Radical Republicans in Congress that demanded serious punishment for the Confederated States for all the damage done in the Civil War. Lincoln just pretended that 10% of people in each state pledge allegiance to the Union to be accepted.
