Answer: B
Diesel is a mixture of \(C_{15}H_{32}\) to \(C_{18}H_{38}\) hydrocarbons.
Diesel fuel is a middle distillate of petroleum boiling roughly between 200 and 350 degrees C, made up mostly of alkanes with about 12 to 20 carbon atoms. Of the ranges offered, \(C_{15}\) to \(C_{18}\) lies squarely within that band.
\(C_{5}\) to \(C_{10}\) compounds such as octane (\(C_{8}H_{18}\)) make up petrol (gasoline), which is lighter and more volatile, and \(C_{20}\) to \(C_{22}\) chains belong to heavier oils and waxes. Option C's \(C_{5}H_{14}\) is not even a possible alkane, since pentane is \(C_{5}H_{12}\).
