Which of the following actions is NOT considered a civic duty?

The action of supporting local businesses is not classified as a civic duty. Civic duties are obligations that each citizen is expected to perform to help ensure the functioning and maintenance of the community and government. These duties typically include activities that contribute directly to the well-being of society and the democratic process.

Defending the nation reflects a commitment to national security and is often seen as a fundamental responsibility of citizens, particularly in the context of military service. Serving on juries is a critical aspect of the judicial system, ensuring that legal proceedings are carried out fairly and justly, which is a direct civic responsibility. Voting in elections is a vital component of democracy, allowing citizens to have a say in their government and influence public policy.

Supporting local businesses, while beneficial to the economy and community, is not mandated or considered a formal civic duty within the same framework as the other actions listed. It is more of a personal or moral choice rather than a civic obligation, making it the correct answer in this context.
