Which of these responsibilities of us citizenship is considered mandatory?
a)holding political office
b)serving in the army
c)serving on a jury
d)joining a political party

Hey!

Hope this helps...

Although everyone would like to see every U.S. citizen do everything on the list, the ONLY mandatory thing you must do, while being a citizen of the United States is serve on the Jury...

If you can recall/remember that it is a Federal Offence to deny serving on the Jury...

So the correct answer is C. )Serving on the Jury

The correct answer is C) Serving on a jury.

Considering that citizens accused of crimes in the United States have the right to have their case heard in front of a jury of their peers, the government requires that citizens participate in jury duty. This responsibility is mandatory for individuals who are called on to serve. Failure to serve will result in legal punishments.

All of the other answer choices are voluntary actions that citizens can take. However, there is no law requiring any of the other actions listed in the other option choices.

all of them lol cause theres no map
