What is a common use for each fraction of crude oil?

Crude oil is separated into various fractions through a process called fractional distillation, where different fractions can be used for a variety of purposes based on their boiling points and chemical properties. The correct answer highlights that fractions of crude oil are commonly used as fuels or feedstocks for the petrochemical industry.

For example, the lighter fractions such as propane and butane are used as fuels for heating and cooking, while kerosene is often used in aviation fuel. Heavier fractions, such as diesel and lubricating oils, are used in transportation and machinery. Additionally, these fractions serve as feedstocks for the production of chemicals and materials in the petrochemical industry, which includes the manufacturing of plastics, synthetic fibers, and many everyday chemicals.

In contrast, the other options are more limited in scope. Generating electricity is typically associated with coal, natural gas, or nuclear energy rather than crude oil fractions. While plastics do originate from petrochemical processes, suggesting that the solely making plastics is an incomplete representation of the versatility of crude oil fractions. Lastly, while some fractions may be used as solvents, this is a much narrower application compared to their broader roles as fuels and feedstocks. Hence, the correct answer encompasses the wide-ranging applications of crude oil fractions beyond
