A given fuel has an octane number of 100. This means that
Answer Details
The octane number is a measure of the ability of a fuel to resist knocking, which is the uncontrolled and explosive combustion of fuel in the engine's combustion chamber. A higher octane number means that the fuel has a greater ability to resist knocking. Therefore, if a fuel has an octane number of 100, it indicates that the knocking tendency of the fuel is low, and it can resist knocking well. Thus, the correct option is "the knocking tendency of the fuel is low."
