The correct option is D The end of European colonialism in Africa
The end of European colonialism in Africa was not an immediate effect of the events surrounding World War II. The end of European colonialism in Africa took place between 1945 and 1960. Decolonization was often affected by superpower competition, and had a definite impact on the evolution of that competition. The start of the world war II in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland.
