Answer:
C
Step-by-step explanation:
D is a tough one to get rid of. There wasn't armed conflict between the superpowers, but there were proxy wars. Egypt was armed by the Soviet Union and Israel by the United States. It was sort of like participating in a football match. You get rid of D only by stating that the conflict was not direct.
The superpowers did not have a policy of cooperation. A is utterly incorrect.
There was no acceptance of Communism. 2 wars (Korean Vietnam) were fought to contain communism. B is wrong
C is the correct answer.
