Why is Ghana's independence called an event that broke a mental barrier in African decolonization?

Correct answer: It showed that an independent nation in sub-Saharan Africa was possible

Answer: A. Ghana, formerly the British Gold Coast, became independent in 1957 under Kwame Nkrumah. Its success gave African nationalists a powerful practical example: colonial rule could be challenged and a self-governing African state could be created. The phrase “mental barrier” refers to the weakening of the belief that European rule was permanent or that independence was impossible. A is correct because Ghana’s independence demonstrated a realistic path for other movements and encouraged wider decolonization. B is wrong because independence reduced British colonial authority in Ghana. C is wrong because the Gold Coast had been under British colonial rule. D is wrong because the partition of Africa occurred earlier, mainly during nineteenth-century imperial expansion. Memory cue: Ghana, 1957, Nkrumah, example for African independence.
