The correct answer to this question is A) an increase in the unemployment rate.
A major problem in South Africa since the end of Apartheid is an increase in the unemployment rate.
Apartheid ended in 1994. Since that time there have been some major problems in South Africa such as the increase in the unemployment rate, poverty has not been reduced, the government hasn't had enough money to invest in education, health, and housing. Another considerable problem has been the gap between the economic possibilities of the white people against the limited economic conditions of the black people.
