In a democracy, the essential feature is giving prominence to the citizen. This means that the power and authority of the government comes from the people, who have the right to participate in the decision-making process. Option 1, the Executive, refers to the branch of government responsible for implementing laws and policies. Option 2, the Judiciary, refers to the branch of government responsible for interpreting and applying laws. Option 4, Civil Society, refers to organizations and groups outside of the government that work towards the betterment of society. While all of these elements are important in a democracy, the ultimate authority lies with the citizens who have the right to vote, express their opinions, and hold their government accountable. Therefore, option 3, Citizen, is the correct answer.
