Brown V Board of Education Was Marked by Gradualism

Brown v. Board of Education was marked by gradualism. In what way did it, the desegregation of the armed forces, and other incremental measures make the inequality they were intended to alleviate problematic?

A) Gradualism in American civil rights has always allowed counter-response that entails setbacks, too.
B) Like "three-fifths of a person," it had all the defects of previous half-measures.
C) Once again, in U.S. history, what could have been a sweeping decision was not made to the detriment of American society.
D) It facilitated a patient, nonmilitant approach that would later feed the riots of the late 1960s and the radical Black Power movement.
