    Answer : Option C

    Explanation :

    Normal heptane fuel detonates readily. Octane number equates to the anti-knock qualities of a comparison mixture of heptane and isooctane which is expressed as the percentage of isooctane in heptane and is listed on pumps for gasoline (petrol) dispensed globally.
