The correct answer is - B. history of segregation and apartheid.

South Africa has had a long history of racial segregation and intolerance, mainly between the white population, and the black Bantu population. This resulted into the society becoming like two different parallel worlds, where whites are living in their own exclusively white neighborhoods, while the black live in their own. The job and education opportunities were not equal for both sides as well. Nowadays, the apartheid is long gone, but now there's a reversed situation, where the black population is taking a revenge on the white population, so now the whites are the ones that have it harder, especially from safety point of view.

a. it led to stricter immigration laws.
