If the voter list is accurate but demarcation is unclear, what deficiency remains?

Correct answer: It will remain unclear which voter elects the representative of which area

Direct answer: A is correct. An accurate voter list tells us who is registered, but it cannot by itself define the geographical constituency. Demarcation is needed to show which territory belongs to which constituency and which representative is responsible for it. If boundaries are unclear, even correctly recorded voters may not know which area’s representative they are choosing or which constituency’s arrangements apply to them. Thus, a reliable election requires both an accurate list and clear boundaries. B is wrong because unclear boundaries do not decide a voter’s age. C is wrong because they do not erase an identity-card photograph. D is wrong because a boundary problem does not automatically close a polling booth. Memory cue: the list identifies voters; demarcation identifies their electoral area.
