If the name in the voters' list is correct but the identity proof has a major mismatch, what challenge may occur during voting?

Correct answer: Difficulty in voter identity verification

Correct answer: A, difficulty in voter identity verification. At a polling station, officials must reasonably verify that the person seeking to vote corresponds to the registered elector. A serious mismatch between the voter-list entry and the identity document can lead to questions, delay, or a need for clarification under the applicable election procedure. The problem is verification, not the drawing of constituency boundaries. Option A is correct because it describes the immediate practical challenge. Option B is wrong because an identity mismatch cannot alter demarcation. Option C is wrong because it has no automatic effect on reservation. Option D is wrong because checking a voter's identity does not add candidates. The name in the roll and proof of identity serve related but distinct purposes: registration establishes inclusion in the roll, while identity checking helps confirm that the person presenting the claim is that elector. Memory cue: correct name plus mismatched identity means verification difficulty.
