Explanation

To match the given graphs with the isobaric process, we need to analyze each graph based on the characteristics of an isobaric process. An isobaric process is defined as a thermodynamic process in which the pressure remains constant.

### Step-by-Step Solution:

1. **Understanding Isobaric Process**:
- An isobaric process is characterized by constant pressure. This means that in a pressure-volume (P-V) graph, the line will be horizontal, indicating that as volume changes, pressure does not.

2. **Analyzing Graph A (P-T Graph)**:
- In the P-T graph, if the line is straight and passes through the origin, it indicates that pressure is proportional to temperature (P ∝ T).
- Since pressure changes with temperature in this graph, it does not represent an isobaric process.
- **Conclusion**: Graph A is **not** isobaric.

3. **Analyzing Graph B (P-V Graph)**:
- In this graph, if the pressure remains constant while the volume changes, it represents an isobaric process.
- A horizontal line in a P-V graph indicates constant pressure.
- **Conclusion**: Graph B is **isobaric**.

4. **Analyzing Graph C (T-V Graph)**:
- For a constant pressure process, the relationship between temperature and volume can be derived from the ideal gas law (PV = nRT). If pressure is constant, volume is directly proportional to temperature (V ∝ T).
- In a T-V graph, this relationship would appear as a straight line. If the graph is curved or not linear, it does not represent an isobaric process.
- **Conclusion**: Graph C is **not** isobaric.

5. **Analyzing Graph D (P-T Graph)**:
- Similar to Graph A, if the pressure remains constant across different temperatures in a P-T graph, it indicates an isobaric process.
- If the graph shows a horizontal line at a certain pressure level, it confirms that pressure is constant for varying temperatures.
- **Conclusion**: Graph D is **isobaric**.

### Final Matching:
- **Isobaric Process**: Graphs **B** and **D**.
- **Not Isobaric Process**: Graphs **A** and **C**.
