The correct answer is D) Soviet expansionist plans.
After the end of World War II, the United States and Soviet Union emerged as global superpowers. To maintain this reputation, both had aspirations to remain global influences by creating alliances and spreading their ideas to other countries. This was especially the case with the Soviet Union and their system of communism.
