Explanation

Water efficiency refers to the amount of water required to produce a unit of crop yield. Among the given options, Sugarcane is well-known for being a highly water-intensive crop. It requires a significant amount of water throughout its long growing period, often making it less water-efficient, especially when compared to crops adapted to drier conditions. Pearl millet (Bajra) and Red gram (Arhar) are rain-fed crops largely grown in semi-arid and arid regions due to their drought-tolerant nature and lower water requirements. Sunflower, while requiring more water than millets or pulses, is generally less water-intensive than sugarcane.
