Answer: C. Brown v. Board of Education of Topeka
Explanation:
Brown v. Board of Education of Topeka was a very important Supreme Court case that stopped the practice of racial segregation in public schools by ruling the practice to be unconstitutional.
As a result, the National Association for the Advancement of Colored People (NAACP) enrolled nine black students in a previously all-white school in Little Rock, Arkansas.
There was so much anger at this from the city's white population and the Governor, Faubus, brought in the National Guard to prevent the children from attending school under the guise of keeping the peace.
