Why can people change leaders in democracy?

Correct answer: Because leaders come through elections

Direct answer: A, Because leaders come through elections. Democratic leaders receive public authority through elections, so citizens can choose to renew or withdraw that authority in a later election. Reasoning: candidates contest an election; voters select among them; the winner forms or joins the government; during the term the leader remains accountable; at the next election voters may support the same leader or choose someone else. A is correct because an electoral mandate makes replacement possible. B, leaders coming by birth, is wrong because hereditary succession does not give citizens a real choice. C, the army ordering it, is wrong because military command is not the democratic source of authority. D, saying vote is unnecessary, is wrong because voting is precisely the method through which citizens select and replace representatives. Elections alone do not guarantee perfect government, but they provide an essential accountability mechanism. Memory cue: elected power can be electorally withdrawn.
