In the correct answer (Option 2):
I-B, Cotton is matched with Rainfall 1500-2000 mm; Temperature 25° - 35°C. Cotton requires a warm climate and moderate rainfall, reflections of these conditions are depicted in this match.
II-C, Flax is matched with Rainfall 600 - 800 mm; Temperature 5° - 18°C. Flax can tolerate cooler conditions and withstand less rainfall conditions reflecting the conditions in this choice.
III-E, Sugarbeet is matched with Rainfall 500 - 600 mm; Temperature 18°- 22°C. Sugarbeets can grow in moderately cool climates and require less rainfall, well-supported by this choice.
IV-D, Jute is matched with Rainfall 500 - 1000 mm; Temperature 18° - 22°C. Jute prefers similar conditions to Sugarbeets but can handle a bit more rain, as suggested in this match.
Other options are not suitable due to mismatch in rainfall-temperature conditions for the respective crops. They do not accurately reflect the climate conditions required for each crop which is why they are incorrect.
