How does omission of an eligible voter's name from the electoral roll affect free elections?

Correct answer: It may deny the voter the right to choose a representative

The correct answer is B: omission can deny an eligible person the practical opportunity to vote. An electoral roll is the official list used to identify people who are entitled to participate in a particular election. A free election requires eligible citizens to be included fairly and to have a real chance to cast their vote. If a person's name is missing, that person may be turned away even though he or she satisfies the legal conditions for voting. The problem is not merely administrative: it directly reduces political participation and makes the principle of equal voting weaker. A is wrong because a missing name does not itself increase campaign spending. C is wrong because the number of candidates is determined through nomination and scrutiny, not by an omitted voter's name. D is wrong because secrecy concerns how a vote is cast, not whether an eligible person is allowed to vote. Memory cue: electoral roll means access to the ballot.
