"They gave generous payments to blacks who agreed to move to Africa or Canada" would not describe a method whites used to keep blacks from exercising their rights, since most actions were discriminatory.
The correct answer is D) They gave generous payments to blacks who agreed to move to Africa or Canada.
The idea of "separate but equal" was implemented in American society after the Supreme Court case Plessy vs. Ferguson ruled that separate facilities for blacks and whites did not violate the 14th amendment.
Black codes were also implemented during the Reconstruction era. The goal of these black codes was to limit the political and social rights of the newly freed African-Americans.
Some white people even formed groups to harass and physically harm African-American citizens. This includes the infamous group of the Ku Klux Klan.
