The correct options are
A Hospitals and ambulances
B Trains and buses
C Housing societies
D Movie theatres
During the apartheid in South Africa, hospitals were separate and so were ambulances. An ambulance meant for white people would always be well equipped while one meant for black people was not. There were separate trains and buses. Even the bus stops were different for black and white people. The white people and the black people did not live together but in separate societies. Even entertainment sources such as movie theatres and parks had such segregations.
