The correct answer is D. The Cold War was a conflict between the United States and the Soviet Union.
Explanation:
Cold War is the designation attributed to the historical period of strategic disputes and indirect conflicts between the United States and the Soviet Union, comprising the period between the end of World War II (1945) and the extinction of the Soviet Union (1991). It was a political, military, technological, economic, social and ideological conflict between the two nations and their zones of influence. It is called "cold" because there was no direct war between the two superpowers, given the unfeasibility of victory in a nuclear battle.
