Assertion (A). Higher yield in case of bell pepper can be achieved by growing them in `CO_(2)` enriched green houses
Reason (R). Due to higher intracellular `CO_(2)` concentration in bundle sheath cells, RuBisCO mainly acts as carboxylating enzyme

Options

A. A is true but R is false
B. A is false but R is true
C. Both A and R are true and R is correct xplanation of A
D. Both A and R are true but R is not correct explanation of A.

Answer

To solve the question, we need to analyze both the Assertion (A) and the Reason (R) provided.

### Step 1: Analyze the Assertion (A)
The assertion states that "Higher yield in case of bell pepper can be achieved by growing them in CO₂ enriched greenhouses."

- **Explanation**: This statement is true because increasing the concentration of CO₂ in greenhouses enhances the photosynthesis process. Higher CO₂ levels can lead to increased rates of photosynthesis, which can result in higher yields of crops like bell peppers.

### Step 2: Analyze the Reason (R)
The reason states that "Due to higher intracellular CO₂ concentration in bundle sheath cells, RuBisCO mainly acts as a carboxylating enzyme."

- **Explanation**: This statement is also true. In plants that utilize the C4 pathway (like maize and sugarcane), the bundle sheath cells have a higher concentration of CO₂, which allows RuBisCO to primarily function as a carboxylating enzyme. This is important because RuBisCO can also act as an oxygenase, leading to photorespiration, which is less efficient. Therefore, in C4 plants, the high CO₂ concentration minimizes this inefficiency.

### Step 3: Determine the Relationship between A and R
Now we need to determine if the Reason (R) correctly explains the Assertion (A).

- While both statements are true, the reason provided does not directly explain why growing bell peppers in CO₂ enriched greenhouses leads to higher yields. The assertion is more about the general effect of CO₂ on yield, while the reason discusses a specific mechanism in C4 plants.

### Conclusion
Based on the analysis:
- Assertion (A) is true.
- Reason (R) is true, but it does not serve as a correct explanation for Assertion (A).

Thus, the correct answer is: **Both A and R are true, but R is not the correct explanation of A.**

### Final Answer
**Option 4: Both A and R are true but R is not the correct explanation of A.**
