⦁ Oil extracted from maize that can be converted into ethanol or biodiesel. Hence, Statement 2 is correct.
⦁ The type of alcohol in the alcoholic drinks we drink is a chemical called ethanol. To make alcohol, you need to put grains, fruits, or vegetables through a process called fermentation. the common source of ethanol is maize and other grains. Hence, Statement 3 is correct.
