**Core Concept**
The Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) provides standardized criteria for diagnosing mental health conditions, including depression. The DSM-IV criteria for depression aim to identify the essential symptoms and characteristics that define this condition.
**Why the Correct Answer is Right**
The DSM-IV criteria for depression include a combination of mood, cognitive, and physical symptoms that must be present for at least two weeks. The core symptoms include a depressed mood most of the day, nearly every day, or a markedly diminished interest or pleasure in activities most of the day. Additionally, at least four of the following symptoms must be present: significant weight loss or gain, insomnia or hypersomnia, psychomotor agitation or retardation, fatigue or loss of energy, feelings of worthlessness or guilt, diminished ability to think or concentrate, and recurrent thoughts of death or suicidal ideation. The symptoms must cause significant distress or impairment in social, occupational, or other areas of functioning.

**Option A:** This option is incorrect because it does not accurately represent the DSM-IV criteria for depression.
**Option B:** This option is incorrect because it is too vague and does not specify the required duration and severity of symptoms.
**Option C:** This option is incorrect because it focuses on a single symptom (depressed mood) without considering the broader range of symptoms required for a diagnosis.
**Clinical Pearl / High-Yield Fact**
