Which of the following best describes a civic duty?

A civic duty refers to responsibilities and actions that are considered mandatory for the functioning of a democratic society. These duties often include activities that are legally required, such as voting in elections or serving on a jury when called. These actions are designed to uphold the principles of democracy and ensure that citizens actively contribute to governance and the legal system.

In contrast, the other choices focus on voluntary engagement or suggestions rather than obligations. For example, engaging in community leadership or group activities can be beneficial but are not mandatory. Similarly, following community rules is important for civic life, but it does not capture the essence of what constitutes a civic duty, which is grounded in legal requirements that protect the rights and responsibilities of citizens within the community. Hence, the answer that aligns precisely with the definition of civic duty is the one that identifies it as a mandated action.
