When were Jim Crow laws first legislated and enforced on Black people?

Jim Crow laws emerged after Reconstruction, especially in the late 1800s, and enforced racial segregation and discrimination for decades, lasting into the 1960s. The 1896 Plessy v. Ferguson ruling upheld segregation but did not mark the beginning of all Jim Crow laws, so choice A is too narrow. The laws also did not begin during colonial slavery or during the civil rights movement.
