What was the cause of the apartheid movement in south africa? nonwhite south africans felt superior to white afrikaners. white afrikaners opposed the blacks-only parliament. a military coup overthrew the south african government. white afrikaners wanted racial separation from black africans.

The correct answer is
White Afrikaners wanted racial separation from black Africans.

There was no blacks-only parliament, Afrikaners held it all and had all the power in the country. This resulted in them feeling superior to Africans and wanted to separate themselves and segregate the Africans from all areas of public living, and this was done with the apartheid politics.
