C. Obsession to perform a compulsive ritual
D. Depression alternates with mania.

Answer

**Step-by-Step Solution:**

1. **Understanding Bipolar Mood Disorder**: Begin by defining bipolar mood disorder. It is characterized by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression).

2. **Identifying the Options**: The question provides four options regarding what occurs in bipolar mood disorder:
- Prolonged depression
- Anxiety and avoidance behavior
- Obsession to perform a compulsive ritual
- Depression alternates with mania

3. **Analyzing Each Option**:
- **Prolonged Depression**: This refers to persistent depressive disorder, which is not a characteristic of bipolar disorder. In bipolar disorder, the depression is not prolonged but alternates with periods of mania.
- **Anxiety and Avoidance Behavior**: This describes anxiety disorders, not bipolar disorder. While individuals with bipolar disorder may experience anxiety, it is not a defining feature of the mood disorder itself.
- **Obsession to Perform a Compulsive Ritual**: This is indicative of obsessive-compulsive disorder (OCD), which is a separate mental health condition. It does not relate to the mood swings seen in bipolar disorder.
- **Depression Alternates with Mania**: This is the defining characteristic of bipolar mood disorder. Individuals experience episodes of depression that alternate with episodes of mania.

4. **Conclusion**: Based on the analysis, the correct answer is that in bipolar mood disorder, "depression alternates with mania."

**Final Answer**: Depression alternates with mania.
