Question

Assertion (A): Bacterium to provide resistance to insects without need for pesticides is biopesticide. Reason (R): The choice of genes depends upon the crop and targeted pest in pest resistance method.

• A. Both (A) and (R) are correct and (R) is the correct explanation to (A)
• B. Both (A) and (R) are correct but (R) is not correct explanation for (A)
• C. (A) is correct (R) is wrong
• D. (A) is wrong (R) is correct

Hint:

Biopesticides allow plants to protect themselves!

Answer 1

The Correct Option is B

Step 1: Restate the parts.
Assertion: a bacterium that gives insect resistance without pesticides is a biopesticide. Reason: the choice of genes depends on the crop and the target pest.

Step 2: Judge the assertion.
A is correct. A bacterium like Bacillus thuringiensis protects the crop from insects naturally, so it acts as a biopesticide.

Step 3: Judge the reason.
R is also correct. When engineering pest resistance, scientists do pick genes based on which crop and which pest they are dealing with.

Step 4: Check the link.
Both are true on their own, but the reason is about choosing genes for resistance crops. It does not explain why the bacterium is called a biopesticide. So R does not explain A.

Step 5: Choose the option.
Both A and R correct, but R is not the correct explanation of A.

Step 6: Conclusion.
Therefore the correct answer is "Both (A) and (R) are correct but (R) is not correct explanation for (A)". \[ \boxed{\text{A and R true, R not the explanation}} \]
