Wich example demonstrates fulfilling a citizenship responsibility rather than an obligation at the state level

I'm going to need more context but i'll give some more information upon this in general:  

---A COMMON GOOD good is something seen as a benefit to the larger community rather than individual interest. YOU DO NOT HAVE TO DO A COMMON GOOD.

--A OBLIGATION is something you HAVE TO DO BY LAW.

- A RESPONSIBILITY is something a person SHOULD DO.

Explanation:

Hope this helps.
