The statement that best analyzes World War II's impact on Nigerian independence is:
"While Nigeria participated in World War II, British officials viewed the colony as key to postwar reconstruction, so they prevented independence."
This statement reflects the historical context in which Nigeria's strategic importance in the war and the postwar period influenced British policies, delaying the country's independence despite the growing nationalist sentiments. The war contributed to a push for independence, but British officials were more focused on utilizing Nigeria's resources for reconstruction.
