Final answer:
OSHA's role in government, as indicated by the notice, is to execute legislation passed by Congress. It sets and enforces safety standards in the workplace through a process involving public engagement. The correct option is B. it has authority to execute legislation passed by congress.
Step-by-step explanation:
The notice illustrates that the Occupational Safety and Health Administration's (OSHA) role in the government is to execute legislation passed by Congress. As an agency of the United States Department of Labor established under the Occupational Safety and Health Act signed into law on December 29, 1970, OSHA's mission is to ensure safe and healthy work conditions. It achieves this by setting and enforcing standards, and by providing training, outreach, education, and assistance.
OSHA is granted authority by Congress to promulgate standards, and before issuing a standard, OSHA engages in a public process including notice and comment. Furthermore, while executive orders may be used to carry out legislation, the role of executive enforcement is to oversee the implementation of laws passed by Congress, and does not extend to interpreting the Constitution as a requirement for OSHA's role.
