The correct answer is D. The Korean War did not change the governments of North Korea and South Korea.
Explanation:
The Korean War was a war between South Korea under Syngman Rhee supported by troops from several western countries and North Korea under Kim Il-Sung with the support of troops from the People's Republic of China.
The war began as skirmishes on the border between north and south. Elections in South Korea were held in May 1950. North supporters did not do well, and North Korea demanded that the elections be re-run. The South refused and on 25 June 1950 North Korean troops moved south to try to reunite the country. The fighting continued until the truce on 27 July 1953.
The North's army had rapid successes, and South Korean troops were forced to retreat. The city of Seoul was occupied by the North Korean army on June 28. A resolution was passed at the United Nations calling on North Korea to retreat from the south. At the time, the USSR had decided not to take part in the United Nations, so could not stop the decision to provide military aid to South Korea. United States troops were the largest contingent of the war, but it was also formed by the United Kingdom, Canada, Australia, New Zealand, France, South Africa, Turkey, Thailand, Greece, Holland, Ethiopia, Colombia, the Philippines, Belgium, and Luxembourg.
At first, the number of US troops was not large, and they were defeated at Osan on 5 July. By August, the south only occupied a small territory in the southeast around Pusan. They managed to hold on to Pusan after a hard fight. More UN troops arrived, and there was heavy bombing by US aircraft. On 15 September they attacked with a landing at Inchon, and Seoul was captured back to South Korea. The troops of the north had to retreat, and the southern and UN forces moved north, with the intention of uniting all of Korea under the government of Syngman Rhee.
As they approached China's border, the Chinese government warned them that it would take part in the war. On 19 October the Chinese troops moved to the border, and on 1 November 1950 they collided with the US forces. South Korean and US troops were forced to retreat south. On 4 January 1951 Seoul was captured by the Chinese army. The city was re-occupied by the United States on March 14. The Communists were eventually sent back to the border between North and South Korea.
From October 1951 to July 1953 the fighting continued without much change in the territory occupied by both sides. Peace talks continued for two years, in Kaesong and then in Panmunjon. A ceasefire was agreed on 27 July 1953, in which a status quo ante bellum was agreed, which meant the consolidation of both North Korea and South Korea in their respective territories.
