A is the answer to this question
All the conflicts in Korean territory have caused the deaths of about four million people, mostly civilians. The peace proposal is accepted by China and signed on July 27, 1953 officially declaring the end of the war. The border that divides South Korea, capitalist, and North Korea, communist, is still maintained today and, despite its demilitarized area, is still the victim of frequent conflict.
Korea would remain divided and the boundaries between the two should be demilitarized. The Korean War dragged on for three long years, the result is a balance of countless deaths on both sides, the conflict was one of the most tense and bloody in the Cold War.
