Why is the system of electing one representative from a constituency useful?

Correct answer: It makes territorial accountability clear

Correct answer: A. A constituency is a defined territorial area whose voters elect a representative. When one representative is linked clearly with that area, residents know whom they elected and whom they can question about local concerns. This creates territorial accountability: the representative is answerable to the voters of that constituency. Option B is wrong because the system depends on voting rather than ending it. Option C is wrong because a voters' list remains necessary to identify eligible voters. Option D is wrong because election does not make a representative permanent; representatives serve for the constitutionally provided term and may have to face another election. The key idea is clear area–clear representative–clear accountability.
