**Core Concept**
The concept being tested is the color-coded triage system used in medical emergencies and disasters. This system is designed to prioritize patients' treatments based on the severity of their conditions. The colors used are typically red, yellow, green, and black.

**Why the Correct Answer is Right**
In the triage system, **green** indicates patients with minor injuries who are unlikely to need significant medical care. These patients are often referred to as the "walking wounded." They may need some basic first aid but do not require immediate medical attention.

**Why Each Wrong Option is Incorrect**
**Option A:** Is incorrect because it does not correspond to the correct color coding in triage.
**Option B:** Does not apply as it is not the standard for green in triage.
**Option D:** Is incorrect as it represents a different category in the triage system.

**Clinical Pearl / High-Yield Fact**
Remembering the triage colors is crucial: **red** for critical, **yellow** for observation, **green** for minor injuries, and **black** for deceased or expectant. This color-coding system helps in quick decision-making during mass casualties.

**Correct Answer:** D. Walking wounded/minor injuries.
