Which measure practically strengthens the principle of 'one person one vote' in polling?

Correct answer: Identity check and ink mark

Direct answer: A is correct. “One person, one vote” means that each eligible voter should cast one vote and that no person should vote more than once. At the polling station, checking the voter’s identity helps confirm that the person is the registered voter whose name appears on the roll. Applying an indelible ink mark records that the person has already voted, making repeated voting more difficult. A: Correct, because identity verification and the ink mark work as practical safeguards for one vote per voter. B: Wrong, because a speech may influence opinion but cannot prevent multiple voting. C: Wrong, because the price of a poster has no connection with voting equality. D: Wrong, because fame does not prove identity and does not give anyone an extra lawful vote. These measures do not decide which candidate a voter chooses; they protect the fairness of the procedure. Memory cue: “Check the person, mark the vote, protect equality.”
