Explanation

To solve the question regarding the CO₂ compensation point and optimum CO₂ concentration for C₃ and C₄ plants, we will follow these steps:

### Step-by-Step Solution:

1. **Understand CO₂ Compensation Point**:
- The CO₂ compensation point is the concentration of CO₂ at which the rate of photosynthesis matches the rate of respiration. Below this level, plants will take in more CO₂ than they release, and above this level, they will release more CO₂ than they take in.

2. **C₃ Plants CO₂ Compensation Point**:
- For C₃ plants, the CO₂ compensation point is relatively high due to the occurrence of photorespiration. The typical range for C₃ plants is between **25 to 100 ppm**.

3. **C₄ Plants CO₂ Compensation Point**:
- C₄ plants have a lower CO₂ compensation point because they are more efficient in photosynthesis and do not undergo photorespiration to the same extent as C₃ plants. The CO₂ compensation point for C₄ plants is generally around **0 to 10 ppm**.

4. **Optimum CO₂ Concentration for C₃ Plants**:
- The optimum CO₂ concentration for photosynthesis in C₃ plants is higher because they require more CO₂ for efficient photosynthesis. This is typically around **450 ppm**.

5. **Optimum CO₂ Concentration for C₄ Plants**:
- For C₄ plants, the optimum CO₂ concentration is lower compared to C₃ plants, and it is generally around **360 ppm**.

6. **Final Values**:
- From the analysis:
- A (C₄ plants CO₂ compensation point) = **0 to 10 ppm**
- B (C₃ plants optimum CO₂ concentration) = **450 ppm**

### Summary of Values:
- A = 0 to 10 ppm
- B = 450 ppm
