Question

has several advantages over ethanol, such as higher energy content, lower water absorption, and better blending ability. a. biodiesel b. butanol c. methanol d. biomass

Explanation:

Butanol has a higher energy content than ethanol. It also has lower water absorption (less hygroscopic) and better blending ability with gasoline compared to ethanol. Biodiesel is a different type of bio - fuel (fatty acid methyl esters) and has different properties. Methanol has lower energy content than ethanol. Biomass is a general term for organic matter used as a fuel source, not a specific fuel like the others in the options.

Answer:

B. Butanol
