Final answer:
The petroleum refining process is an example of a continuous production process, involving separation, conversion, and treatment steps to create various products, including gasoline. Hence, option (c) is correct.
Step-by-step explanation:
The process of breaking down crude oil into several marketable products such as gasoline, heating oil, and aviation fuel is an example of a continuous production process. In a refinery, crude oil undergoes separation, conversion, and treatment to produce different fractions like propane, butane, diesel, and lubricating oil. This is done using large-scale fractional distillation where crude oil is heated and its components are separated by their boiling points.
Moreover, treatments such as cracking and reforming are used to manipulate chain lengths and create more valuable products. The collected fluids are then turned into a variety of applications including fuels and lubricants, with gasoline being a prime product.
