Which of the following is an exception to rights granted to non-citizens?

The correct answer highlights a specific limitation placed on non-citizens in the context of their rights within the United States. Non-citizens are not permitted to serve on juries, which is a foundational civic duty and responsibility reserved for citizens. This exception underscores the legal and civic distinction between citizens and non-citizens, where certain rights and responsibilities, particularly those that contribute to the justice system and governance, are exclusively granted to citizens.

The other options represent rights that do not typically apply to non-citizens. For example, holding public office and voting are both privileges specifically reserved for citizens. Likewise, the concept of staying in the U.S. unconditionally is not accurate, as non-citizens are subject to immigration laws and requirements, which can limit their ability to remain in the country. This distinction further reinforces the unique status of citizens in relation to both participation in democracy and legal responsibilities.
