Which of the following is considered a key feature of a democratic society?

A key feature of a democratic society is the right to vote. This foundational aspect of democracy allows citizens to participate actively in the political process by selecting their representatives and influencing legislation. The right to vote ensures that power rests with the people, reflecting their preferences and interests in governance. It promotes accountability and helps maintain a system where leaders can be chosen based on the will of the electorate.

While freedom of trade, social media control, and mandatory military service can play roles in various governance systems, they do not define the core democratic principle of citizen participation through voting. In a democratic context, the right to vote serves as a crucial mechanism for ensuring that government actions are aligned with the values and needs of the population, thereby fostering an engaged and informed citizenry.
