The correct answer is (4) political divisions established between
communist and noncommunist territories

In Korea, it split the country between the North Koreans who were communists and the southerners who were capitalists, while in Vietnam it split them also into Northern communists and Southern non-communists. However, in Vietnam the communists eventually won while in Korea the parallel still exists today and the country is split.
