C. FEMA Administrator

Explanation:

According to my research on Incident command Strategies, I can say that based on the information provided within the question all of these responsibilities fall under the FEMA Administrator's job. FEMA is the Federal Emergency Management Agency, and their Administrator is in charge of all of these responsibilities as well as assisting the President and the Secretary of State with information and assistance in response to terrorist attacks and major disasters.
