Repeated unclear changes in election rules weaken which democratic element?

Correct answer: Transparency and trust in the process

Correct answer: B, transparency and trust in the process. Election rules tell citizens and candidates how registration, campaigning, voting, and counting will take place. Rules should be known, understandable, and applied consistently. If authorities repeatedly change rules without clear reasons or notice, people may not know what to expect. Candidates may also feel that the process is being adjusted unfairly. This weakens transparency because the procedure becomes difficult to examine, and it weakens trust because people may suspect unequal treatment. Option A is irrelevant because voter height has no democratic meaning. Option C is not the answer: candidate age may be a fixed eligibility condition, but the question concerns unclear changes in rules generally. Option D is irrelevant because a polling-station wall does not determine fairness. Memory cue: clear, stable, equally applied rules build electoral trust.
