Which statement accurately describes one reason a delegation of authority may be needed?
A. When the incident scope is complex or beyond existing authorities
B. If the Incident Commander is acting within his or her existing authorities
C. To specify the Incident Action Plan to be implemented by the Incident Commander
D. To relieve the granting authority of the ultimate responsibility for the incident
A, When the incident scope is complex or beyond existing authorities.
Explanation:
Delegation of authority means passing the power to the level where it is required or practiced better than the existing holders of the authority.
So according to this question, a delegation of authority is needed where the incident scope is complex, which means that this could not be understood by the current or existing authorities clearly, or the incident scope is beyond the existing authorities which means the incident scope does not come within the power range of the authorities. So in such scenarios, the best solution is to delegate authority to those who are within the scope of the incident and also they understand it pretty well.
