If one constituency has too many voters and another has very few voters, which concern may arise?

Correct answer: The balance of representation may be affected

The correct answer is D. In a representative democracy, each constituency usually elects a representative, so a very large difference in population can create a concern about equality of representation. A representative elected by a very small number of voters may represent far fewer people than a representative elected by a very large number. This does not automatically prove that an election is invalid, because boundaries may involve constitutional, geographic or administrative considerations, but it raises an important fairness question. A is wrong because population size does not automatically change ballot language. B is wrong because voters do not all become candidates; candidacy has separate eligibility rules. C is wrong because unequal constituency size does not abolish the voting age. D is correct because it identifies the central democratic concern: whether citizens receive reasonably balanced representation. Memory cue: “Unequal population per seat can mean unequal representative weight.”
