Hi there!
The correct answer is C) Civil and political rights of blacks and whites are equal.
Explanation:
Jim Crow laws enforced racial segregation in the South of the U.S. He mandated racial segregation in all aspects and they were upheld until 1896 and were followed by the "<em>separate but equal</em>" doctrine, which guaranteed equal protection under the law to all people.
Segregation is defined as the act by which someone separates other people on the foundation of one of the enumerated grounds with an objective or any reasonable justification. Plessy v. Ferguson, a landmark decision of the U.S. upheld this racial segregation laws for public facilities as long as these facilities were equal in quality.
Although these laws guaranteed these equality between races, the social prejudice of black people was badly seen for the rest of the society (white people). This did not guarantee this "<em>social equality</em>", because this is built by society not by law. If white people did not considered black people as equal to them, the law could not do anything about it. The law only covered civil and political sameness.
