Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the term used for serial changes occurring in a previously sterile or barren area.

2. **Identifying Key Terms**: The key terms here are "serial changes," "previously sterile," and "barren area."

3. **Defining Succession**: Succession refers to the process of change in the species structure of an ecological community over time.

4. **Types of Succession**:
- **Primary Succession**: This occurs in lifeless areas where there is no soil, such as bare rocks or sand dunes. It starts from scratch.
- **Secondary Succession**: This occurs in areas where a disturbance has destroyed an existing community but soil and some organisms still remain.

5. **Analyzing the Options**:
- **Option A (Climatic Climax)**: This refers to the final stage of succession, not the initial changes in a barren area.
- **Option B (Secondary Succession)**: This involves recolonization of an area that was previously occupied, not a barren area.
- **Option C (Primary Succession)**: This is the correct answer as it describes changes starting from a barren area.
- **Option D (Seed)**: This is not relevant to the question.

6. **Conclusion**: The serial changes in a previously sterile or barren area are referred to as **Primary Succession**. Therefore, the correct answer is **Option C**.
