<em>A. Guaranteeing all African American males the right to vote.</em>
Explanation:
After the American Civil War, the Reconstruction began. One of the biggest topics during this time was whether or not the South should be punished and take blame for their actions. While some people wanted to forgive the South and move on, some wanted the South to pay.
The Radical Republicans played a big role in the Reconstruction. They believed in equal rights for African Americans and black males ended up with the right to vote. They also wanted to punish Confederate leaders for their crimes during the war and embrace equality among the country.
President Lincolns plan for Reconstruction was very different from the Radical Republicans' idea. While the Radical Republicans thought that the South should pay for what they did, President Lincoln believed that if they took an oath to the Union they should get off free.
