Maintaining order in society is an example of
a. providing for the common defense
b. establishing justice
c. insuring domestic tranquility
d. promoting the general welfare

I think the best answer is c. insuring domestic tranquility (if you have order, there is little chance for riots and other kinds of disturbances), although I would say that trying to maintain  oder at all costs (see totalitarian states) can actually sometimes have the opposite effect.

The answer is closed primary.
