What resources are assigned to every response package?

In the context of response packages, the correct answer identifies the key personnel necessary for an effective incident management and response strategy. Assigning an APL (Accountable Project Lead), a fire investigator, and one additional project manager (PM) ensures that there is a balance of leadership, technical expertise, and operational support.

The APL serves as the primary leader responsible for overseeing the whole response package, ensuring that all resources are utilized efficiently. The inclusion of a fire investigator is crucial as they bring specialized knowledge needed to assess and understand fire-related incidents, contributing significantly to incident analysis and strategy. Adding an additional PM supports the logistics and coordination of the response efforts, allowing for a more streamlined and effective approach to incident management.

This staffing structure enables a comprehensive response by combining leadership, expertise, and operational capacity, which are essential for successful incident resolution. The other choices may not align with the optimal resource distribution necessary for handling and investigating incidents effectively.
