The best classification for the given sample of crude oil, based on the percentages of different hydrocarbons, is **a mixture**.
Crude oil consists of various types of hydrocarbons (paraffins, naphthenes, aromatics, and asphaltics) in different proportions, which is characteristic of a mixture rather than a pure substance, a pure compound, or an element.
