b) pardoned southern leaders for civil war actions.
c) hoped to reunite the country as quickly as possible.
d) regarded the southern states as conquered territory.

The correct answer is D) regarded the southern states as conquered territory.

Following the Civil War, the Radical Republicans in Congress regarded the southern states as conquered territory.

Radical Republicans in Congress did not agree with President Lincoln's plans to reunite the country as quickly as possible. President Abraham Lincoln wanted a quick Reconstruction process and gave leeway to the Southern states to do their own Reconstruction process and only demanded the application of the 10th percent Plan, issued on December 8, 1863. So the attitude of the radical Republicans following the Civil War was that the Southern States had been conquered and should be punished by their actions.
