Answer:
A. No actual fighting occurred
Step-by-step explanation:
The term "cold" is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. It was called the Cold War because neither the Soviet Union nor the United States officially declared war on each other. However, both sides clearly struggled to prevent the other from spreading its economic and political systems around the globe. The Cold War began after World War Two. The main enemies were the United States and the Soviet Union. The Cold War got its name because both sides were afraid of fighting each other directly. It was also to prevent Communism around the world and mainly Cuba.
