Final answer:
Without specific answer choices, it's challenging to determine which option is NOT a way in which today's U.S. business organizations differ from a century ago. In general, contemporary businesses emphasize technology, globalization, and modern regulations, which were not prevalent a century ago.
Step-by-step explanation:
Today's business organizations in the U.S. significantly differ from those a century ago in several ways. However, without the specific options provided to identify which is NOT a way in which they differ, it is difficult to give a definitive answer. Generally, contemporary businesses are characterized by their use of advanced technology, focus on globalization, and adherence to regulations such as diversity and environmental policies that were not present or as developed a century ago. We also see greater emphasis on corporate social responsibility and work-life balance in modern times. Therefore, any option that suggests these characteristics were also a central aspect of businesses a century ago would likely be the correct answer.
