Final answer:
The Korean War resulted in the continued division of the Korean Peninsula into communist North Korea and noncommunist South Korea, with no unification achieved. The North grew increasingly isolated, while the South maintained and developed its ties with the West.
Step-by-step explanation:
The result of the Korean War was option (a): a communist North Korea and a noncommunist South Korea. Following World War II, the Korean Peninsula was divided along the 38th parallel into two zones controlled by the Soviet Union in the North and the United States in the South. This post-war division led to two separate governments, each aligning with the ideology of their respective superpower's influence—communism in the North and capitalism in the South.
With the end of the Korean War, which lasted from June 1950 to July 1953, the Korean Peninsula remained divided. Despite the involvement of the United Nations and the participation of various nations under the UN flag, led by the United States, no decisive victory was achieved and the pre-war boundary approximately along the 38th parallel was essentially maintained. Following the war, North Korea and South Korea developed separately, with North Korea becoming increasingly isolated under communist rule, while South Korea fostered economic growth and maintained political ties with the West, especially the United States.
