Explanation: Nelson Mandela was an anti-apartheid activist and head of the African National Congress Party. He was the first black president of South Africa, elected in 1994 after years of imprisonment for his anti-apartheid activities. Even though F. W. de Klerk worked to repeal apartheid laws after his election as South Africa’s president in 1989, as he was a white politician, his presidency didn’t symbolize the end of apartheid (A). There was no major bombing of Lesotho (C). The Boer War was fought by the British and the Boers (Dutch descendants) for control of South Africa at the end of the 1800s, and is therefore out of the time period.
