How does the presence of opposition parties in elections help make government accountable?

Correct answer: They criticise government policies and present alternatives

The correct answer is B. Opposition parties scrutinise the government, point out weaknesses in its policies and present different programmes or solutions. This gives citizens information for judging the government and a possible alternative at the next election. Criticism alone is not the whole role of opposition; it also includes offering another choice and representing views that may differ from the ruling party. A is wrong because opposition parties do not exist to stop all voters. C is wrong because hiding results would reduce transparency, not increase accountability. D is wrong because removing voter lists would deny participation. Memory cue: opposition means criticism plus an alternative, giving voters a way to review and replace the government.
