D: voting in a Presidential election.

Registering with the selective service is an obligation, and while volunteering at a community food bank and being involved in issues on college campus is great, voting in a presidential election is a responsibility of citizens in a democracy, as by participating in a democracy you strengthen it. Democracies are systems of governments where the officials are elected by the people.
