Answer:
A. Communism
Step-by-step explanation:
Since North Korea is controlling both the economy and the country (more properly, state) as a whole, that makes it communist. Utopianism is the idea that the society is perfect, and North Korea isn't perfect, nor is any state around the globe. It isn't Capitalist because it controls everything (in essence). It isn't Socialism, since, again, it controls everything.
