If a voter's name is in the roll but identity proof is not satisfactory what is the polling officer's main duty?

Correct answer: Verify identity according to rules

Correct answer: C. A name in the electoral roll shows that a voter record exists, but the polling officer must also follow the prescribed identity-verification requirements. If the offered proof is not satisfactory, the officer’s duty is to seek clarification or apply the relevant rules before allowing the vote. C is correct because it protects both the voter’s right and the integrity of the polling process. A is wrong because voting without the required check could permit impersonation or an irregular vote. B is wrong because campaigning is not allowed as a substitute for verification and is a different election activity. D is wrong because counting happens after polling closes, not while voter identity is being checked. The safe principle is: eligibility on the roll and identity according to rules must both be respected.
