Answer:
D) Strict schedules for workers.
Step-by-step explanation:
The mechanization of the 19th-century workplace led to increased efficiency and production, but also often resulted in strict schedules and more rigid control over workers. While some workers may have gained more stable employment, the conditions of work were often harsh and exploitative. The rights of workers and the standard of living for the laboring class improved gradually over time, but it was a long and ongoing process that was only partially realized in the 19th century.
