What is one characteristic of a democratic government?

In a democratic government, one defining characteristic is political control by all people, which encompasses the idea of popular sovereignty. This means that the authority of the government is derived from the consent of the governed, typically exercised through free and fair elections. Citizens have the right to vote on various matters, including the election of representatives and the formulation of laws, thereby allowing them to participate actively in the political process. This collective involvement ensures that the government reflects the will and interests of the populace.

The other choices highlight features that are generally associated with authoritarian regimes rather than democratic ones. A singular leader or a concentration of power in a central authority indicates lack of public input and potential oppression of dissent, both of which are contrary to democratic principles. Additionally, lack of citizen votes eliminates the very foundation of democracy, where the people's voice is essential in shaping governance and policy-making.
