What is a key characteristic of a democracy?

A key characteristic of a democracy is that citizens have voting rights. In a democratic system, power resides with the people, and one of the fundamental ways citizens exercise this power is through the right to vote. This enables individuals to participate in the decision-making process regarding their government and its policies. Voting rights ensure that diverse opinions and interests can be expressed and considered, reflecting the will of the majority while also protecting the rights of minorities.

In contrast, the other provided options do not align with the principles of democracy. One-party rule typically characterizes authoritarian regimes where dissenting voices are suppressed. A government that makes all decisions and centralized decision-making systems limit citizen participation and undermine democratic values, as they restrict public input and accountability.
