AI Explanation
The correct answer is B) heating value. The heating value of a fuel oil is a measurement of its available energy content, which is a key property for determining the fuel's suitability and efficiency for various applications. The heating value, also known as the calorific value, represents the amount of energy released when the fuel is completely burned. The other options are incorrect: A) Cetane index and D) Cetane number are measures of the ignition quality of a diesel fuel, not its energy content. C) Viscosity index is a measure of how the viscosity of a lubricating oil changes with temperature, and is not related to the fuel's energy properties.
