What is one responsibility of U.S. citizens?

One of the key responsibilities of U.S. citizens is paying taxes. This obligation is fundamental to maintaining the functions of government and providing essential services to the public, such as infrastructure, education, and national defense. By contributing to the tax system, citizens support the financial needs of various government programs and services that benefit society as a whole.

This responsibility is critical for ensuring that the government can operate effectively and uphold the rights and privileges afforded to its citizens. While other options may be rights or additional responsibilities associated with citizenship, paying taxes is unique in that it is a legal obligation that directly sustains the country's operations.
