**Core Concept**
The question pertains to disaster management, which involves a multidisciplinary approach to mitigate the effects of disasters, such as natural calamities, accidents, or human-made catastrophes. Effective disaster management requires a coordinated response from various stakeholders, including medical professionals, emergency responders, and government agencies.

**Why the Correct Answer is Right**
The correct answer is not provided, so let's assume the question is asking us to identify the incorrect statement among the options. In disaster management, the principles of triage are crucial in allocating resources and prioritizing patients. The triage categories include:

* **Immediate**: Patients who require immediate medical attention to save their lives.
* **Delayed**: Patients who can be treated after immediate care has been provided to those in the immediate category.
* **Urgent**: Patients who require medical attention but are not in immediate danger.
* **Expectant**: Patients who are unlikely to survive despite medical intervention.

**Why Each Wrong Option is Incorrect**
Since the options are not provided, let's create some hypothetical distractors:

**Option A:** In disaster management, the primary goal is to save as many lives as possible, even if it means diverting resources from those who are unlikely to survive.
* This statement is incorrect because, in disaster management, the primary goal is not just to save lives but also to allocate resources efficiently and prioritize those who are most likely to benefit from medical intervention.

**Option B:** The principles of triage are not applicable in disaster management.
* This statement is incorrect because the principles of triage are indeed applicable in disaster management, where resources are limited, and decisions must be made quickly to prioritize patients.

**Option C:** In disaster management, the "Urgent" category is the same as the "Delayed" category.
* This statement is incorrect because the "Urgent" category and the "Delayed" category have distinct meanings in disaster management. The "Urgent" category refers to patients who require medical attention but are not in immediate danger, whereas the "Delayed" category refers to patients who can be treated after immediate care has been provided to those in the immediate category.

**Option D:** The "Expectant" category is not used in disaster management.
* This statement is incorrect because the "Expectant" category is indeed used in disaster management to refer to patients who are unlikely to survive despite medical intervention.

**Clinical Pearl / High-Yield Fact**
In disaster management, the principles of triage are crucial in allocating resources and prioritizing patients. The triage categories should be remembered using the mnemonic "IMDU" (Immediate, Delayed, Urgent, Expectant).
