Yes, it's c.

The correct answer is C. Communist governments had taken over the northern parts of the countries.

During the Cold War, the spread of communism was a major concern for the United States and its allies. In the cases of Vietnam and Korea, the Cold War spread to these countries mainly because communist governments had taken over the northern parts.

In Vietnam, after the defeat of French colonial forces in 1954, the country was divided into two parts: North Vietnam, which was governed by communist forces led by Ho Chi Minh, and South Vietnam, which was under the control of a pro-Western government. The United States supported South Vietnam, fearing that the spread of communism in the region would threaten U.S. interests. The conflict in Vietnam escalated into a full-scale war between the communist North and the U.S.-backed South, known as the Vietnam War.

In Korea, the division between North and South Korea came about after World War II. The Soviet Union occupied the northern part of the Korean peninsula, establishing a communist government under Kim Il-sung, while the United States occupied the southern part, supporting a pro-Western government. Tensions between the two sides led to the Korean War, which lasted from 1950 to 1953 and became one of the major battlegrounds of the Cold War.

While Chinese and Soviet involvement did play a role in these conflicts, the initial spread of communism in Vietnam and Korea was primarily due to the establishment of communist governments in the northern parts of these countries.
