Correct answer & explanation
✓
Incident response plan
The incident response plan (IRP) defines roles, responsibilities, and escalation paths for incident handling, addressing the lack of a clear chain of command. Option B (business continuity plan) focuses on maintaining critical business functions during a disruption, not incident response command structure. Option C (security awareness training material) educates users on security policies, not on incident command. Option D (network topology diagram) depicts network layout, not decision-making hierarchy.
