Final answer:
W. E. B. Du Bois is most accurately described as having emphasized the importance of civil rights and social equality for African Americans. He opposed racial segregation, challenged Booker T. Washington's strategies, and was a founder of the NAACP.
Step-by-step explanation:
Among the statements about W. E. B. Du Bois's beliefs, the true one is that C) He emphasized the importance of civil rights and social equality for African Americans. Du Bois was a pivotal figure in the fight for civil rights and was strongly against racial segregation. He was the first African American to receive a Ph.D. from Harvard University and used his education to advocate for equality. Du Bois challenged Booker T. Washington's approach, which he saw as an accommodation to white supremacy through acceptance of segregation. He founded the NAACP, contributed to sociological investigations of Black life in America, and sought to lift African Americans through a liberal arts education, as depicted in his promotion of "the talented tenth" concept.
Contrary to endorsing segregation or the superiority of one race over another, W. E. B. Du Bois actively opposed these notions and fought for the integration and equal treatment of African Americans. He did not support colonialism or imperialism but instead worked towards ending racial discrimination and promoting African Americans' social and political rights.
