The correct answer is A. Citizens elect leaders who vote on the issues in a representative democracy, and citizens vote on the issues in a direct democracy.
Step-by-step explanation:
Democracy is a type of political system in which the decisions are directly or indirectly made by the citizens. Due to this, democracy can be classified as direct democracy if the citizens are the ones that vote to made the decisions as it occurs in town meetings in which people from a community gather and directly decide on issues of the community or as indirect democracy in the case citizens select representatives that should defend citizens' interests and decide on issues as it occurs in the case of presidents, governors, mayors, etc.
Thus, the main difference between these two concepts is that in representative democracy citizens elect leaders, while in direct democracy citizens directly decide (Option A).
