**Step-by-Step Solution:**

1. **Understanding Pith**: Pith is a central part of the stem or root in plants, primarily composed of parenchyma cells. It serves various functions, including storage and support.

2. **Analyzing the Options**: The question provides four options regarding where pith is well developed:
- Dicot stem and monocot root
- Monocot stem and dicot root
- Monocot root and monocot stem
- Dicot root and dicot stem

3. **Pith in Dicot Stem**: In dicot stems, the pith is well developed. This is due to the presence of parenchyma cells, which are abundant in this type of plant structure.

4. **Pith in Monocot Stem**: In contrast, monocot stems do not have a well-developed pith; in fact, pith is absent in monocot stems.

5. **Pith in Dicot Root**: In dicot roots, the pith is present but poorly developed compared to that in dicot stems.

6. **Pith in Monocot Root**: Monocot roots, however, do have a well-developed pith, similar to dicot stems, which is also made up of parenchyma cells.

7. **Conclusion**: The only option that correctly states where pith is well developed is the first option: "Dicot stem and monocot root."

**Final Answer**: Pith is well developed in dicot stem and monocot root.
