If an official decision is not available for review, which value weakens?

Correct answer: Accountability and transparency

Review makes public decisions open to checking by a court, supervisor, oversight body, or affected person. If an official knows that the decision can be examined, the official is more likely to follow rules, explain the reasons, and avoid personal favour or arbitrary action. Review also allows errors and unfair treatment to be challenged.

The question says that an official decision cannot be made available for examination at all. This weakens both accountability and transparency, so option D is correct. Polling-booth arrangements, election dates, and campaign permission are separate electoral matters. A system without review makes it difficult to know whether power was used lawfully or whether a person’s rights were ignored.
