The correct answer is D) Egypt.
The African nation that was finally freed from Britain in 1922, after protests, is Egypt.
Great Britain issued the Unilateral Declaration of Egyptian Indipence on February 28, 1922. Egypt has gained its independence from the United Kingdom. Egypt was no more a protectorate of the English.
