Question

Assertion A: Break of monsoon at critical stages for soil moisture stress leads to reduction in yield.
Reason R: Only when the break of monsoon exceeds 15 days duration or more.
In light of the above statements, choose the correct answer from the options given below:

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

Hint:

Monsoon break: dry spell during rainy season.
Critical stages: flowering, grain filling.
Yield reduction due to moisture stress.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Break of monsoon affects crop growth.
The duration of the break determines the impact.

Step 2: Key Formula or Approach:
No specific formula.
Need to understand monsoon breaks and their effects.

Step 3: Detailed Explanation:
Assertion A: Break of monsoon at critical stages leads to yield reduction.
This is true.
Reason R: Only when the break exceeds 15 days.
This is also true.
However, the reason (15 days) is not the explanation for yield reduction.
Yield reduction occurs due to moisture stress regardless of the exact duration.
Thus, both are true, but R is not the correct explanation of A.

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