Explanation

Maize is a versatile crop used industrially to produce starch through wet milling, its oil serves as a feedstock for biodiesel via transesterification, and its high carbohydrate content allows for fermentation into alcoholic beverages like bourbon. Option (b) is the most tempting wrong choice for those who might overlook maize's role in the beverage industry, despite it being a globally recognized substrate for ethanol and spirit production.
