Answer:
The correct answer is C. According to W.E.B. DuBois, the first element of prosperity is justice.
Step-by-step explanation:
Du Bois addressed in his writings the inequities of education and justice, which he considered the fundamental pillar on which to sustain the prosperity of the African-American community. He considered these issues a consequence of the ravages of slavery and the emerging capitalist system.
DuBois was convinced that, once justice was obtained, that is, all equality between blacks and whites, African Americans could assert their rights and reach their prosperity and improve their living conditions.
