Which of the following is produced in areas where water is not available for corn to survive?

Sorghum is particularly well-suited for areas with limited water availability, which makes it a more viable crop compared to others like corn, wheat, and hay under such conditions. This drought-tolerant cereal grain has evolved to withstand arid environments and can thrive in conditions where other crops struggle to survive due to insufficient moisture.

Sorghum's characteristics, such as deep roots and a unique structure that allows it to utilize water efficiently, contribute to its ability to grow in environments that may not support traditional crops. This resilience not only helps it to yield harvests in regions facing water scarcity but also makes sorghum a suitable choice in climates where irrigation is impractical.

In contrast, corn typically requires significant water for optimal growth and is less adaptable to dry conditions. Wheat has moderate water needs but does not possess the extreme drought resistance that sorghum has, while hay usually consists of grasses or legumes that also benefit from adequate moisture levels to produce good yields. Therefore, when water is scarce, sorghum stands out as the most appropriate crop to grow.
