Correct answer: C — Priority 3 (green)

In primary triage, an ambulant adult is generally categorised as P3 unless there are overriding features or local tool modifications. The open fracture needs care but can tolerate delay compared with non-ambulant physiological compromise. This distinguishes triage priority from injury severity in isolation.
