a. Communists rule North Korean-China and the Soviet Union back North Korea
Explanation:
During the 1950s and 1960s, the world became divided into two spheres of influence. On the one hand, some countries chose to be capitalists, with the United States and Western Europe being their main influence. On the other hand, communist countries were often supported by the Soviet Union. In the case of North Korea, the fact that the country decided to be communist led to it being supported by the Soviet Union.
