Correct option is B
The crops have varying water requirements, and their needs are typically ranked from highest to lowest based on their growth stages and water dependency:
1. Rice (B): Requires the highest water input, especially in flooded conditions.
2. Wheat (A): Requires less water compared to rice but still significant.
3. Cucurbit (D): Requires moderate water but not as much as rice and wheat.
4. Sorghum (C): Requires the least water, as it is a drought-resistant crop.
Correct order: B → A → D → C.
