what is a requirement of all citizens in the united states?\no everyone must register with the selective service system.\no everyone must be available to serve on a jury in response to a summons.\no everyone must cast a vote in all municipal, state, and federal elections.\no everyone must volunteer for community service.
Answer
Answer:
B. Everyone must be available to serve on a jury in response to a summons.
Brief Explanations:
In the U.S., when summoned for jury - duty, citizens are legally required to be available. Not all citizens are required to register with the Selective Service (only eligible males). Voting is a right but not a mandatory requirement for all elections. Community - service volunteering is not a legal requirement for all citizens.
