The correct answer is letter A
North Korea is a country formed through the division of ancient Korea, fragmented in 1948, according to the geopolitical interests of the United States and the Union of Soviet Socialist Republics (USSR), giving rise to the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea).
The creation of these two new countries occurred during the Potsdam Conference, where the dividing line was established - Yalta and Ptstan, in the 38 ° parallel. Therefore, two autonomous nations were created with opposing geopolitical ideologies: North Korea, with a communist system, supported by the Soviet Union; and South Korea, capitalist, supported by the United States.
