Final answer:
Attending civic meetings is a responsibility, not a legal obligation, for citizens, and contributes to active participation in democracy. In contrast, paying taxes, obeying the law, and registering for selective service are all obligations under U.S. law.
Step-by-step explanation:
The act considered as a citizenship responsibility, rather than an obligation is c. attending civic meetings. This is because it is something that you are encouraged to do to participate actively in democracy and contribute to society, but it is not legally required. On the other hand, options a. paying taxes, b. obeying the law and d. registering for selective service are all legal obligations under U.S. law, and failing to do them can incur penalties.
