AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Answer: C
Assertion (A) is false — the Green Revolution did NOT lead to uniform development; it concentrated development in a few selected areas. Reason (R) is true as stated in the textbook.
The textbook clearly states: "The Green Revolution based on the use of package technology…led to the concentration of development in few selected areas." This directly contradicts Assertion A (which claims development was "widespread and uniform"), making A false. Reason R correctly describes the nature of the Green Revolution, so R is true. Hence option C is correct.
