Answer

To solve the question "Primary root is the direct elongation of the:", we will analyze the options provided and identify the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Primary Root**:
- The primary root is the first root that emerges when a seed germinates. It plays a crucial role in anchoring the plant and absorbing water and nutrients from the soil.

2. **Identifying the Origin of the Primary Root**:

- **Option 4: Stamen**: This is the male reproductive part of a flower. It has no relation to the root system and is therefore incorrect.

4. **Conclusion**:
- Based on the analysis, the primary root is the direct elongation of the **Radical**.

### Final Answer:
The primary root is the direct elongation of the **Radical**.
