The jure segregation is the pre-civil rights that mandated the segregation of the races and skin color.  It was a common practice in the US that African Americans and White Americans are not allowed to mingle with each other, thus created the law of Segregation.

E is correct answer.

Explanation:

De Jure segregation is the legally enforced separation of groups of people. De Jure means according to the law. The Jim Crow laws in the southern states from the 1800s until the 1960s and the apartheid laws of South Africa are the example of De jure Segregation. It is different from de facto segregation, in which the segregation occurs as a personal choice. Jim Crow laws in the united states enforced racial segregation in the southern region post-civil war. The laws even prohibited marriage between blacks and whites.
