All of the following countries have democratic forms of government except a. japan b. taiwan c. china d. mongolia

C. China

China has some democratic elements; however, China could still be considered a Communist Nation.

The correct answer is c. China.

Officially at least, aside from China, the other three have democracies. China is still partly a communist country, kind of a nice mixture of communism and capitalism, that obviously turned out great for their economy and development as a country, to come to a point of being a world power in every aspect.
