The correct response regarding the success of the Freedmen’s Bureau in South Carolina is:
It failed to improve the economic lives of Black South Carolinians.
While the Freedmen's Bureau made some efforts to address issues such as education and labor contracts, it faced significant challenges and limitations, and many Black South Carolinians did not see substantial improvements in their economic conditions. The other options regarding voting rights and social equality also had significant obstacles, and while there were some successes, the overall impact was mixed.
