What is a voter identity card used for?

Correct answer: To verify a voter's identity

Correct answer: D, to verify a voter's identity. A voter identity card, commonly called a Voter ID, is an identity document used during the voting process. A person first needs to be registered in the electoral roll, and identity verification helps election officials check that the person appearing at the polling station is the same registered voter. The card itself does not create the right to vote if the person's name is absent from the voter list; it mainly helps establish identity. A is wrong because a manifesto is a document describing a party's promises and policies. B is wrong because political parties are formed under legal and organisational procedures, not by using a voter card. C is wrong because constituency boundaries are decided through delimitation, not by individual voters' identity cards. D is correct because it directly describes voter identification at the polling station. Memory cue: Voter ID means identity at voting time; delimitation means changing boundaries.
