Answer:
A) refining the production process and creating greater efficiencies.
Step-by-step explanation:
The production era (1860s - 1920s) started with the industrial revolution since for the first time products could be mass produced at a relatively low cost. Most companies produced only one (or a few) products at a time, and the whole business idea was that something could be produced, someone would purchase it. By the end of this era, companies were focused on being more efficient (scientific method) and reducing their costs while increasing their output.
