Answer

Brief Explanations:

A mixture is composed of two or more substances in any proportion. The sample of crude oil contains paraffins, naphthenes, aromatics, and asphaltic hydrocarbons in different percentages. An element is a pure substance made of only one type of atom. A pure compound consists of two or more elements chemically combined in a fixed ratio. A pure substance is either an element or a compound. Since crude - oil has multiple hydrocarbons in varying percentages, it is a mixture.

Answer:

a mixture
