Under the Stafford Act

A. The Secretary of Homeland Security is responsible for coordinating Government response efforts.

B. The President may designate an incident as either an "emergency" or a "major disaster."

C. The FEMA Administrator may assume the authorities of local, tribal, and State authorities on a temporary basis.

D. The Federal Government may provide unlimited Federal assistance to jurisdictions.

Answer: (B)

Under the Stafford Act, the President may designate an incident as either an "emergency" or a "major disaster."

Explanation:

The Stafford Act allows the President to classify an incident that has occurred, or is about to occur, as either a "major disaster" or an "emergency".

This only occurs if the state in which the incident happens is not capable of handling the incident on its own.

After such a declaration, the Federal government can then render assistance to those affected in form of disaster relief materials or funds.
