Correct answer: A. Relation of accountability and transparency
Explanation: The direct answer is A: the relation between accountability and transparency becomes weak. Democracy is not complete merely because people vote. Citizens also need information about government decisions, spending, policies and results. The fact chain is: information allows citizens to understand what the government is doing; understanding allows them to question and judge it; public judgement makes leaders accountable. Without information, people cannot properly check whether promises were fulfilled or public money was used correctly. Option A is correct because transparency means openness and access to information, while accountability means explaining actions and accepting responsibility. Option B, geography and climate, is unrelated to citizens checking government. Option C, tax and trade, concerns economic matters and does not identify the democratic problem described. Option D, dynasty and succession, concerns hereditary rule, not public information. Remember: no information means no effective public checking; transparency supports accountability.
