The national guard arriving in new orleans to maintain order in the wake of hurricane katrina, is an example of what? a republican form of government, protection against invasion, enforcement of the state constitution, or protection against domestic violence

The answer is protection against domestic Violence

Domestic violence is the violence that occur within households in an area. After a hurricane, there is a pretty high probability that the people in that area might hurt each other in order to survive ( they might steal from each other)

That's why the national guard need to maintain order
