- Both (A) and (R) are correct and (R) is the correct explanation to (A)
- Both (A) and (R) are correct but (R) is not correct explanation for (A)
- (A) is correct (R) is wrong
- (A) is wrong (R) is correct
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Biopesticides and transgenic crop engineering.
Step 2: Meaning
Evaluating statements on agricultural pest management.
Step 3: Analysis
Using bacteria to provide insect resistance is indeed a biopesticide approach (A is correct). The selection of specific genes for this process is dependent on the target crop and pest (R is correct), but the reason does not explain *why* the bacterium's use is considered a biopesticide.
Step 4: Conclusion
Both are true, but (R) is not an explanation for (A).
Final Answer: (B)
