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 how World War II influenced British attitudes towards their colonies, including Nigeria, and the strategic importance the British placed on maintaining control over Nigeria in the postwar period. Nigeria's participation in the war and its resources were seen as valuable for reconstruction efforts, ultimately delaying independence.
