Which of the following best defines "totalitarianism"?

The definition of "totalitarianism" accurately emphasizes the state's attempt to control virtually every aspect of public and private life. In a totalitarian regime, the government not only regulates the political sphere but also extends its influence into the economy, culture, education, and even personal beliefs and values. This comprehensive reach aims to suppress dissent, eliminate opposition, and enforce ideological conformity among its citizens.

In contrast, options that describe a political system with limited government control, a democracy prioritizing individual freedoms, or a government where power is shared with citizens fail to capture the essence of totalitarianism, which is marked by an overarching and oppressive state authority that seeks to dominate every detail of its citizens' lives. Thus, the focus on complete state control makes the second choice the best definition of totalitarianism.
