Ethanol blended in proportion of 10% with gasoline is called:

Correct option is D

Gasohol refers to a blend of gasoline and ethanol. Specifically, when ethanol is mixed with gasoline in a ratio of 10% ethanol and 90% gasoline, it is commonly called E10, or simply gasohol. The ethanol component helps reduce harmful emissions and can serve as a renewable alternative to fossil fuels.

Information Booster:

• Gasohol: The term "gasohol" is often used to describe a mixture of gasoline and ethanol, with the most common mixture being 10% ethanol and 90% gasoline (E10). This blend is widely used in many countries to reduce reliance on pure gasoline, promote cleaner emissions, and utilize ethanol, which is derived from renewable resources like corn, sugarcane, or other plant materials.
• Biodiesel: Biodiesel is a renewable fuel made from organic materials such as vegetable oil or animal fats. It is used as an alternative to diesel fuel, not gasoline.
• Synthetic Natural Gas (SNG): Synthetic natural gas is produced through processes such as coal gasification or biomass conversion, but it is not a blend of ethanol and gasoline.
• Hydrogen Fuel: Hydrogen fuel refers to hydrogen gas used as a clean source of energy. It is not related to the ethanol-gasoline mixture and is used in fuel cells or combustion engines designed to use hydrogen.

Additional Knowledge:

• Ethanol and Environmental Impact: The use of ethanol-blended fuels like gasohol has been promoted for their environmental benefits, as ethanol burns cleaner than gasoline, leading to a reduction in harmful emissions such as carbon monoxide, volatile organic compounds (VOCs), and greenhouse gases like carbon dioxide.
• E10 vs. Higher Ethanol Blends: While E10 (10% ethanol and 90% gasoline) is the most common ethanol blend, higher ethanol blends such as E15 (15% ethanol) and E85 (85% ethanol) are also available in some markets. These higher blends are generally used in flex-fuel vehicles designed to handle them.
