What purpose does the CDC's National Institute for Occupational Safety and Health serve?

The correct answer reflects the primary mission of the CDC's National Institute for Occupational Safety and Health (NIOSH), which is to ensure safe and healthy working conditions for employees. NIOSH conducts research and makes recommendations for the prevention of work-related injuries and illnesses. This includes studying workplace hazards, developing safer work practices, and providing guidance on occupational health standards.

The focus of NIOSH is on promoting worker safety through scientific research and evidence-based solutions that support the well-being of employees across various industries. By prioritizing the health and safety of workers, NIOSH plays a crucial role in reducing workplace accidents and illnesses, which is essential for improving overall public health and productivity.

Other options may address important areas of public health or worker welfare, but they do not accurately represent NIOSH's core functions and objectives.
