The answer is B. They wanted to rebuild Southern states in cooperation with Republican reformers.
Step-by-step explanation:
After the end of the Civil War, the Reconstruction period began, this period involved important changes in the Southern states such as policies to guarantee civil rights and equality. These policies proposed mainly by the Republican Party. Additionally, one of the groups that supported the reconstruction in alliance with Republicans was the scalawags or white southerners who believed in equality and civil rights. Additionally, due to their position about reconstruction scalawags were widely attacked by supremacists groups such as the Ku Klux Klan because they "betrayed" southern values and Democratic ideas of the time. Thus, scalawags "wanted to rebuild Southern states in cooperation with Republican reformers".
