Answer:
D. The Brown case integrated schools, but it did not eliminate the discriminatory treatment of black children.
Explanation:
Oliver Brown's legal fight ensured that schools for white and black children are integrated, so that black kids can go to whatever school they chose, even those who are traditionally attended by white children and therefore and considered better, higher in quality and with a higher level of prosperity.
However, this did no end the bad treatment of the black children in those schools. They were still met with racism and discrimination, usually bullied and stripped back of certain privileges that white children had.
