I'm not sure but i think D would be correct, hope this helps some :)
The answer is B.
It cannot be A since in Gordimer's "Occasion for Loving" Gideon conveys a Black character who openly struggles with his White relationships. He knows he will never have freedom to love Ann.
It cannot be C since in "The Lying Days" traces of how her own mother took care of Black African children with her own daycare center were highlighted.
Letter B is denied in "No Time Like the Present" wherein Steve and Jabu fight against the poor education system the South African government offers.
They probably think like there frustarated or something (the character not them) the the reader probably would be weirded out or questionable or also frustrated
I think that the answer should be d. Believe it or not Joe, it is time for us to leave.
