The correct answer is C. South Africa
Step-by-step explanation:
"The apartheid" was a legislation system that promoted racial segregation and that took place from 1948 to 1990 in South Africa. During this period, the country legislation was based on "white supremacy" which is the idea that white people are superior and should dominate people from other races mainly promoted by the National Party of this country. Because of this, "The apartheid" included multiple ways of segregation and oppression to nonwhite citizens who were the majority of the population in contrast to the minority of white people that dominated the country. This included important violations to rights including human and politic rights in all South Africa. However, since the 1990s and especially since 1997 with the end of the National Party the government of this country has gone through multiple changes and negotiations that supported the progress towards equality in South Africa. Thus, the country in which the rights of nonwhite citizens were restricted under the "apartheid" and since 1997 made progress towards equality is South Africa.
