Which of the following is not a responsibility of U.S. citizens?

Voting at the state level is not categorized as a legal responsibility of U.S. citizens in the same way that paying taxes, obeying laws, and serving on a jury are. Responsibilities of citizenship typically refer to duties that citizens are required by law to fulfill.

Paying taxes is a legal obligation imposed by the government to fund services and programs. Obeying laws is fundamental to maintaining order and safety in society; failure to comply can result in legal penalties. Serving on a jury is also a civic duty that citizens must engage in when called upon, as it is a critical component of the judicial system.

Voting is a privilege and a right afforded to citizens, but it is not deemed an obligatory action. While it is encouraged for citizens to participate in elections as a means of exercising their voice and influence in government, failing to vote does not carry legal consequences. This distinction helps clarify why voting at the state level is not registered as a responsibility similar to the other three options.
