3. (B) Apartheid ends in South Africa: The negotiations to dismantle the institutionalized system of racial segregation in South Africa took place in the early 1990s, leading to the repeal of apartheid laws in 1991 and culminating in the country's first fully representative democratic elections in April 1994.
