Why is a queue system maintained at polling stations?

Correct answer: To give every voter a fair opportunity to vote in turn

Correct answer: A. A queue gives voters an orderly and fair turn to enter the polling area, complete identity and procedural checks, and cast a vote without pushing, confusion, or unfair preference. It is a simple administrative arrangement that protects equal access and helps polling proceed peacefully. Option A is correct because every voter should receive a comparable opportunity to vote. Option B is wrong: the purpose is not to stop voting but to manage it efficiently. Option C is wrong because a polling station is for voting and election administration, not for campaigning; campaigning there could influence or disturb voters. Option D is wrong because a queue has no connection with changing counted results. A useful cue is: queue means order before voting, not control over the result.
