B. The change game following the U.S. Supreme Court's ruling to desegregate schools.

Explanation:

In 1954, the Supreme Court issued the famous judgement in Brown vs Board of Education which ruled that segregation in schools was unconstitutional and so should cease with immediate effect.

Georgia, a southern state with a legislature that was full of segregationists, resented this and in an act of defiance, passed the bill for the adoption of the 1956 Georgia flag which incorporated elements of the Confederate flag which has come to be known as a symbol of white supremacy.
