The correct answer is A) control by foreign powers.
Read the resolution adopted by the United Nations General Assembly in 1960. "The subjection of peoples to alien subjugation, domination, and exploitation constitutes a denial of fundamental human rights."
In the resolution, the words “alien subjugation, domination, and exploitation” most likely refer to control by foreign powers.
The United Nations had realized that one of the most important international issues that had to be solved in the 1960s was precisely the subjugation of many underdeveloped nations that were under the control and influence of other powerful countries. That is why the General Assembly of the United Nations adopted that resolution.
