Answer:
D). Families of the same race live in the same neighborhood.
Step-by-step explanation:
De facto segregation is exemplified as the separation of people into groups based on the facts or customs that exist in reality instead of enforced legal separation. Such segregation(racial or ethnic) occur due to increased societal disparity and differences.
As per the question, option D exemplify 'de facto segregation' as the families of the same race have separated themselves factually and circumstantially. They were not enforced or bound by any legal requirement or legislation to get separated. The people have themselves adopted a distinct path(segregation) to avoid the societal differences and establish their own community. Thus, option D is the correct answer.
