The correct answer is D) Both black children and adults attended the schools.
The statements describe the schools started by the Freedmen's Bureau during Reconstruction is "Both black children and adults attended the schools."
The Bureau supported African American people to attend school. It established schools for poor black people; elementary and higher education institutions for African American people and poor white people. Christian institutions such as the American Missionary Association supported this education effort. However, this decision generated resentment and conflicts in the southern states because many white people opposed the changes.
