### Step-by-Step Solution:

1. **Understanding Auxins**: Auxins are important plant growth regulators that play a crucial role in regulating various growth activities in plants.

2. **Production of Auxins**: Auxins are naturally produced in specific regions of the plant. They are primarily synthesized in the meristematic regions, which are areas of active cell division.

4. **Analyzing the Options**:
- **Shoot**: This option is too vague as it does not specify which part of the shoot is being referred to. Therefore, it cannot be considered correct.
- **Meristematic region of stem or root**: This option is accurate because auxins are indeed produced in the meristematic regions of both the stem and the root. This is the correct answer.
- **Root leaf buds**: This option is also vague and does not specify which part of the root or leaf buds is being referred to, making it incorrect.

5. **Conclusion**: Based on the analysis, the correct answer is that auxins are abundantly produced in the **meristematic region of stem or root**.

### Final Answer:
Auxins are abundantly produced in the **meristematic region of stem or root**.
