**Core Concept**
The **DSM-4**, or Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, is a manual used for psychiatric diagnoses. It utilizes a **multiaxial system** to assess various aspects of a patient's condition. This system allows for a comprehensive evaluation of an individual's mental health.

**Why the Correct Answer is Right**
The DSM-4 employs a **five-axis system**. Axis I includes clinical disorders and other conditions that may be a focus of clinical attention. Axis II comprises personality disorders and mental retardation. Axis III covers general medical conditions. Axis IV assesses psychosocial and environmental problems. Axis V evaluates the individual's global functioning.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it underestimates the number of axes.
**Option B:** This option is also incorrect as it does not accurately reflect the number of axes in the DSM-4.
**Option D:** This option overestimates the number of axes.

**Clinical Pearl / High-Yield Fact**
The **multiaxial system** in DSM-4 is crucial for a thorough psychiatric evaluation. Remember, the five axes provide a comprehensive framework for assessing clinical disorders, personality disorders, general medical conditions, psychosocial problems, and global functioning.
