Explanation

To determine the correct diagram regarding the acidic strength of the oxides CO2, N2O5, SiO2, and P4O10, we need to analyze the acidic character of these non-metal oxides based on their non-metallic character and size.

### Step-by-Step Solution:

1. **Identify the Oxides**: The oxides given are CO2 (carbon dioxide), N2O5 (dinitrogen pentoxide), SiO2 (silicon dioxide), and P4O10 (tetraphosphorus decoxide).

2. **Understand Acidic Strength**: Non-metal oxides are generally acidic in nature. The acidic strength of these oxides increases with increasing non-metallic character and decreases with increasing size.

3. **Analyze Each Oxide**:
- **CO2**: Carbon is a non-metal and has a relatively small size. It exhibits acidic properties when dissolved in water, forming carbonic acid (H2CO3).
- **N2O5**: Nitrogen is more non-metallic than carbon and has a smaller size compared to phosphorus. N2O5 is a strong acid forming nitric acid (HNO3) in water.
- **SiO2**: Silicon is less non-metallic than nitrogen and is larger in size than carbon. SiO2 is amphoteric but can show some acidic behavior.
- **P4O10**: Phosphorus is larger than silicon and has a lower non-metallic character compared to nitrogen. P4O10 is also acidic, forming phosphoric acid (H3PO4) in water.

4. **Rank the Acidity**:
- From the analysis, we can rank the acidic strengths as follows:
- N2O5 > CO2 > SiO2 > P4O10
- This indicates that as we move from N2O5 to P4O10, the acidic strength decreases.

5. **Select the Correct Diagram**: Based on the ranking, the correct diagram should show an increase in acidic strength from CO2 to N2O5, followed by a decrease from N2O5 to P4O10, and then SiO2 being less acidic than CO2.

### Conclusion:
The correct option is **Option A**, which correctly represents the trend in acidic strength: CO2 < N2O5 > P4O10 > SiO2.
