The correct option is C To provide fair oppportunity
Critical development efforts cannot succeed without a legitimate and democratically elected government that is responsive and accountable to its citizens. Elections provide an important opportunity to advance democratization and encourage political liberalization. Elections offer a choice and fair opportunity to the people to change the current rulers; this choice and opportunity is available to all the people on an equal basis. The exercise of this choice leads to a government limited by basic rules of the constitution and citizens’ rights. Hence, Option A is correct. The rest of the options are the features of elections, not the advantages, hence, incorrect.
