Answer: D) Service.
Explanation: While nationalism is somewhat implied in sentence, it is not the most important concept here. The speaker is taking a familiar idea (concern about what a government can do for the individual) and turning it around to underline the importance he gave to service (what the individual can do for the common good). The option "inquiry" is only related to the word "ask" as a synonym, but it is not relevant semantically.
