Model Answer
Option A is correct. Both A and R are true, and R is the correct explanation of A.
Rice requires annual rainfall above 100 cm, but development of a dense network of canal irrigation and tubewells has made it possible to grow rice in low-rainfall areas like Punjab and Haryana.

Explanation
- The passage directly states rice needs rainfall above 100 cm, but "in areas of less rainfall, it grows with the help of irrigation."
- It specifically mentions that "development of dense network of canal irrigation and tubewells have made it possible to grow rice in areas of less rainfall such as Punjab, Haryana."
- So R correctly and directly explains A — choose Option A, not B.
