South africa’s population registration act of 1950
a. led to the relocation of 600,000 white citizens
b. created a race-based classification system
c. combined several black and white communities
d removed all racial categories from government

I think the correct answer from the choices is option B. South Africa’s Population Registration Act of 1950  created a race-based classification system. This act required that all South Africans be classified according to racial characteristics. This gave rise to racial segregation. Hope this answers the question.
