A voter's name in two constituencies can be a risk to which democratic principle?

Correct answer: One person, one vote, and the accuracy of the list

Correct answer: A. Democratic elections follow the principle that each eligible person should have an equal opportunity to cast one vote, subject to the election rules. If the same person is entered in two constituencies, the electoral record becomes inaccurate and safeguards against duplicate registration may be weakened. The entry does not automatically prove that two votes were cast, but it creates a risk and must be corrected through the proper electoral process. A is correct because it connects duplicate registration with the one-person-one-vote principle and with list accuracy. B is wrong because hereditary rule concerns the transfer of power by family, not voter records. C is wrong because a duplicate entry does not end reserved seats. D is wrong because it does not change the legal voting age. Memory cue: one voter should have one valid electoral entry for the relevant place.
