The correct answer here is D. This was perhaps the most famous phrase used by W.E.B. Du Bois.
Du Bois believed very strongly that African Americans needed to stop being dependent on white people. He did not think that they could simply rely on whites to grant them rights. One of the major ways in which he thought that African Americans could do this was by creating a group of educated blacks who would be able to pull the rest of the race up to their level over time. This group was to be taken from the "talented tenth" of the African American population.
