The most accurate response is:
Activists used nonviolent and violent protests to bring attention to apartheid and put pressure on the government for decades, until the government dismantled the policies.
This answer reflects the reality of the anti-apartheid movement, which included a mix of nonviolent protests, civil disobedience, and armed resistance by various groups over many years. Figures like Nelson Mandela and organizations like the African National Congress (ANC) played crucial roles in mobilizing both strategies to combat apartheid and ultimately achieve its dismantling.
