The answer is C: North Korea.
Nowadays, North Korea is a country ruled by an autocratic ruler (that is to say, a kind of government where one person has all the power, in this case, a dictator) in a one-party system (the Workers´ Party of Korea), in what is called the Kim Dynasty (nowadays Kim Jung Un is the Chairman and absolute ruler of the country). The Kim Dynasty has ruled the country since 1948.
