Final answer:
Work simplification is an approach to job design that seeks to enhance efficiency by streamlining tasks, not by increasing their complexity or enriching or rotating jobs.
Step-by-step explanation:
Work simplification is an approach to job design that focuses on streamlining tasks to enhance efficiency within organizations. In regards to the provided options, the true statement about work simplification is that it streamlines tasks for efficiency (C). Unlike job rotation, enrichment, or increasing task complexity, work simplification is about reducing the complexity of tasks so that they can be performed more quickly and with less effort. This methodology is a part of scientific management, which aimed to increase workers' efficiency, a concept developed by Frederick W. Taylor and others to optimize labor productivity by scientifically studying work methods and establishing best practices.
