C: an informed and active membership in a political community
Citizenship is defined as "the position or status of being a citizen of a particular country", according to Google. This means that as long as you are an active member of the country, you get protection at home and abroad in exchange for your allegiance to the respective country's government.
C) informed and active membership in a political community
There's much more to being a citizen than just about paying taxes, and reaping benefits.
And being a citizen also doesn't mean you get to control every aspect of the government.
Citizenship doesn't just exist in the United States, you can be a citizen of other countries. Not everyone who lives in the United States is a citizen of the United States.
Therefore, the most appropriate answer choice is C.
