HURRY! What was one requirement of President Lincoln's plan for Reconstruction?

-Half of a state's population had to swear an oath of loyalty.

-Confederate military officers had to pay harsh penalties.

-All Southern states had to abolish the practice of slavery.

-Confederate leaders could not take part in state government.

All Southern states had to abolish the practice of slavery.

Explanation:

Lincoln's outline for Reconstruction incorporated the Ten-Percent Plan, which indicated that a southern state could be readmitted into the Union once 10 percent of its voters made a solemn vow Of Allegiance to the Union. Voters could then choose representatives to draft modified state constitutions and set up new state governments.

All southerners aside from high-positioning Confederate armed force officers and government authorities would be conceded a full exoneration. Lincoln ensured southerners that he would secure their private property, however not their slaves. Most moderate Republicans in Congress upheld the president's proposition for Reconstruction since they needed to convey a quick end to the war.

The answer is

C. All southern states had to abolish the practice of slavery.
