Final answer:
A steel company that keeps its blast furnaces running non-stop is an example of a continuous option (c) production system, characterized by a persistent operation that is essential for maintaining efficiency and product quality.
Step-by-step explanation:
The steel company whose blast furnaces operate continuously, except when malfunctions occur, exemplifies a continuous production system. Unlike intermittent production systems, which operate on an as-needed basis, or analytic and synthetic systems that respectively break down or combine materials, continuous production is characterized by a non-stop process.
This method is key in industries where the machinery and production process must remain constant to maintain efficiency and product quality. Continuous production is typical in facilities like those described, where a ceaseless operation ensures the ongoing manufacture of goods, and the description vividly paints how these facilities keep their fires burning and machinery sounding with a relentless, rhythmic cadence.
