Answer:
Booker T. Washington and W.E.B. Du Bois had very different ideas on how to fight segregation. Washington believed in accepting discrimination for the time being and working so hard that the white population would give black people equal rights. W.E.B. Du Bois believed in political and social action, including accepting black people into colleges.
So, the two were not untied (A), and only Du Bois believed in the "talented tenth" (B). I don't think either of them were a part of the Back-to-Africa movement, but I could be wrong.
I think the best answer is D.
