Why is a candidate's affidavit useful for voters?

Correct answer: It makes necessary information about the candidate public

Direct answer: A candidate’s affidavit is useful because it makes required information about the candidate public. Such disclosure can help voters know relevant details presented in the prescribed election process and compare candidates more carefully. Information supports transparency and allows citizens to make a more informed choice, though voters should consider the information critically and not rely on slogans alone. Option C is correct because it describes the affidavit’s disclosure function. Option A is wrong because an affidavit does not change the age of a voter. Option B is wrong because polling-station arrangements are made through election administration, not by a candidate’s affidavit. Option D is wrong because an affidavit cannot decide the result before voters cast their votes and the votes are counted. Memory cue: an affidavit discloses, transparency informs, and voters decide.
