What is one of the three basic ICS components that always apply to every incident?

• A. Unity of command
• B. Incident command post
• C. Span of control
• D. You always report to one supervisor

Answer: (D)

Unity of command means that every member on the incident scene answers to one supervisor only. This single-reporting structure keeps directions clear and accountability intact, which is essential for safety and effective management no matter how large or small the incident is. The statement you’re choosing reflects that principle directly: you always report to one supervisor. The other ideas describe different aspects of ICS—where command is located (the incident command post) or how many people a supervisor can oversee (span of control)—but they don’t capture the guaranteed one-person supervisory line that applies to every incident.
