The Plessy v. Ferguson Supreme Court ruling established the legal basis for racial segregation under the doctrine of "separate but equal." The image you are referring to likely illustrates this concept or its consequences.
If the image suggests that segregation was widespread or indicates the existence of Jim Crow laws, it likely aligns with the notion that these laws were seen as legal and not discriminatory under the ruling at the time. Thus, the most fitting response based on your provided options would be that "Jim Crow laws are not discriminatory."
However, if the image also depicts the expansion of segregation practices beyond the southern states, then "Segregation spread to the northern states" could also be applicable. Please choose the response that best matches the specific context of the image.
