Question

Assertion A: The main aim of topping and desuckering operations is to divert the energy and nutrients of the plants from flower head to leaves.
Reason R: These activities are done to influence the yield and quality of tobacco.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Topping and desuckering: tobacco operations.
Aim: divert energy to leaves.
Improves yield and quality.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Topping and desuckering are cultural operations in tobacco.
They are done to improve leaf quality.

Step 2: Key Formula or Approach:
No specific formula.
Need to understand the purpose of topping and desuckering.

Step 3: Detailed Explanation:
Topping removes the flower head.
Desuckering removes side shoots.
The aim is to divert energy from flower head to leaves.
This improves leaf size and quality.
Thus, Assertion A is correct.
These activities are done to influence yield and quality.
Thus, Reason R is also correct.
However, the reason (influence yield and quality) is not the explanation.
The explanation is the diversion of energy.
Thus, both are correct, but R is not the correct explanation of A.

Step 4: Final Answer:
Both A and R are correct but R is NOT the correct explanation of A.
Hence, the correct option is (B).
