The political ideology that is described in the given question is 'totalitarianism'.
Answer: Option D
Explanation:
The common difference between fascism and totalitarianism is that though fascism functions by keeping the idea of nationalism above everything else, it lacks a solid guiding ideology in its operations. Whereas, in a totalitarianism regime, there is clarity about how the nation is to be run.
In totalitarianism, the authority is not divided between various people. It is exercised by a single person who controls all the governmental and non-governmental agencies. Presently, there are only two countries in all over the world that have totalitarian regimes. They are namely Eritrea and North Korea.
