Answer:
C) The Freedman's bureau
Step-by-step explanation:
The Freedmen’s Bureau was an American agency established by Congress on March 3, 1865, in order to provide practical aid to millions newly freed African Americans in their transition from slavery to freedom, as well as poor whites in the South after the Civil War ended.
The agency achieved to provide medical aid, housing and food for the needed, to provide employment to former slaves and to make changes in the education area, which was one of its major success: The bureau built over 1,000 of schools for blacks and spent over $400,000 to establish teacher-training institutions. It also helped to found colleges that still operate nowadays.
However, the agency couldn't carry out all of its initiatives because of the lack of funding and most of it was disbanded in 1869, while the education section continued until 1872.
