Which of the following is included in the 5 W's that a report should answer?

• A. Who
• B. How
• C. Which
• D. Whose

Answer: (A)

The five W's guide a complete incident report: who, what, when, where, and why. Among these options, the element that belongs to that set is who, because it identifies the person or people involved in the incident or report. How is not part of the canonical five W's; it refers to the method or process rather than the basic questions. Which and Whose aren’t among the five W's either—Which is a selection term, and Whose denotes ownership. In practice, you’d note who reported or responded to the incident and who was involved, ensuring the report clearly names the people connected to the event.
