Which of the following is a responsibility of a citizen?

Paying taxes, fulfilling jury duty, and voting in elections are fundamental responsibilities of citizenship. These duties are essential to the functioning of a democratic society. Paying taxes provides necessary funding for public services and infrastructure, while jury duty is a civic obligation that ensures the legal system functions fairly and justly. Voting in elections is a critical way for citizens to express their opinions and influence government policies, ensuring that elected leaders represent the will of the people.

The other options do not encapsulate the comprehensive responsibilities of a citizen. Participating only in charitable events, for instance, does not reflect the civic duties related to governance and public life. Choosing not to engage in government matters undermines the participatory nature of democracy and the importance of being active in civic affairs. Lastly, only voting in presidential elections disregards the variety of other elections (such as local, state, and midterm elections) and forms of civic participation that are also crucial for a well-functioning democracy.
