Which leader was most closely associated with South Africa's democratic struggle?

Nelson Mandela

Correct answer: D, Nelson Mandela. Nelson Mandela was one of the most important leaders associated with the struggle against apartheid and the creation of democratic South Africa. He opposed racial domination and became a central symbol of equal citizenship, political freedom, and reconciliation. D is correct because the question asks specifically about South Africa's democratic struggle. A is wrong because Mahatma Gandhi is chiefly associated with India's anti-colonial movement, although he had an earlier connection with South Africa. B is wrong because Jawaharlal Nehru was a major Indian leader, not the principal leader of South Africa's anti-apartheid struggle. C is wrong because Abraham Lincoln was a United States president associated with the American Civil War and the abolition of slavery. Memory cue: Mandela—South Africa, apartheid, democracy.
