C: Physical force is sometimes necessary to fight oppression.
Mandela would likely agree with this statement based on his experiences as an anti-apartheid activist. He was involved in founding Umkhonto we Sizwe, the armed wing of the African National Congress, as a response to the violent repression of protests against apartheid. While he advocated for peaceful protest and negotiations, he also recognized that in some circumstances, particularly against oppressive regimes, physical force might be a necessary means to achieve liberation and justice.
