Mutual aid agreements a. are mandated in state and county emergency management budgets. b. assist agencies and jurisdictions when existing resources are inadequate. c. base their assistance on the equivalent monetary value of shared resources. d. are limited to the exchange of resources between neighboring states.

Option B.

Explanation:

Assist agencies and jurisdictions when existing resources are inadequate, is the right answer.  

Mutual aid is an agreement among contingency responders to present support beyond jurisdictional borders. This may transpire due to an accident acknowledgement that passes local sources, including a crash or a multiple-alarm round. This aid may be beseeches only when such urgency befalls. However, Mutual Aid Agreements aid companies and jurisdictions when surviving resources are incompetent.
