Answer C
Washington promised to encourage African Americans to become skilled in common labor and not push for social equality.
From 1895 to 1915, Booker T. Washington was viewed as African Americans' leading spokesperson. He thought African Americans should focus more on economic self improvement than overtly challenging white supremacy.
As said by T. Washington, social equality would follow economic prosperity. He proposed white business leaders to consider hiring African Americans and to provide investment opportunities to black businessmen.
In summary, what accommodation meant to Booker T. Washington, was creating a social space in which blacks could flourish economically while declining to pursue social equality, that´s the reason white southern businessmen and plantation owners supported him..
