Answer:
B. national emergencies
Step-by-step explanation:
The three tiers of government are: federal, state and local government. The federal government has an influence over the state and the state government has an influence over the local government. Any national concern is under the watch of the federal government, and it is beyond the state. Those issues would be handled by the appropriate federal ministry.
From the given options, only the national emergencies can not be handled at the state level. They would be handled by the required federal ministry, because it is a national issue.
