Correct answer: C. Citizens are the source of power
Explanation: The direct answer is option C: citizens are the source of power. In a democratic system, the word “people” does not merely name a population; it explains where legitimate political authority comes from. Citizens exercise this power by voting, choosing representatives, taking part in public discussion, and holding rulers accountable. Option C is correct because democratic rulers govern with authority that ultimately comes from citizens. Option A is wrong because democracy does not reserve power for rich people. Option B is wrong because officers may administer laws, but they are not the original source of political authority. Option D is wrong because hereditary power passes through a family and does not depend on the equal choice of citizens. Citizens may delegate power to representatives, but they do not permanently surrender their rights. Exam cue: in a definition of democracy, “people” points to popular sovereignty—the people are the ultimate source of power.
