Which organization was established in 1941?

The organization established in 1941 is the National Joint Apprenticeship and Training Committee (NJATC). This committee was formed to promote and enhance the quality of apprenticeship training within the electrical industry. It focuses on creating strong apprenticeship programs and ensuring that they meet industry standards, thereby supporting workforce development in the electrical trade.

The other options represent significant organizations but were established at different times. The National Fire Protection Association (NFPA) was founded earlier, in 1896, focusing on fire safety standards. The Occupational Safety and Health Administration (OSHA) was created later, in 1970, to ensure safe working conditions. The National Institute for Occupational Safety and Health (NIOSH) was established in 1970 as well, aimed at conducting research and making recommendations for the prevention of work-related injury and illness. Thus, B is indeed the organization that aligns correctly with the year 1941.
