Answer:
c. student busing
Step-by-step explanation:
Due to housing inequality and the segregation of neighborhoods, students did not receive equal educational opportunities and public schools were separated by race.
In order to right this and racially integrate the schools, students began to be assigned and transported to different schools within or outside of their local school district.
The desegregation busing of students was upheld by the Supreme Court's decision in 1954, in the case of Swann v. Charlotte-Mecklenburg Board of Education.
