Final answer:
Natural gas is not a product of crude oil refining; it is extracted separately. The process of refining crude oil yields other products such as gasoline, diesel oils, kerosene, and liquefied petroleum gas.
Step-by-step explanation:
The process of crude oil refining produces a variety of products. All of the following are products of crude oil refining except natural gas. The correct option is A) Natural gas. Crude oil refining involves processes such as distillation, cracking, and reforming, which result in products such as gasoline, diesel oils, kerosene, liquefied petroleum gas (LPG), and lubricants. These products vary by the chain length of hydrocarbons they contain. Natural gas, primarily made up of methane and ethane, is extracted separately and is not a product of the crude oil refining process.
