Which of the following groups is protected by OSHA standards?

The correct answer reflects that OSHA (Occupational Safety and Health Administration) standards provide protection to specific groups of workers, and it recognizes certain industries that are covered under its regulations. While mine workers are specifically mentioned due to separate regulations for mining under the Mine Safety and Health Administration (MSHA), the inclusion of public servants indicates a broader concern for worker safety in various sectors, including governmental roles.

OSHA's protections extend to workers in a range of industries, but not all employees fall under its jurisdiction equally. In addition, certain groups, such as self-employed individuals or certain farm workers under specific conditions, may not be covered by OSHA. Therefore, while public servants and mine workers are included under OSHA's mandate, the terminology related to 'public servants' illustrates a broader vision of worker protection.

The other options imply limitations on the scope of OSHA's reach. Governmental employees and employees in private corporations are not entirely capturing the entirety of whom OSHA protects, and there is also no exclusive provision for only those workers listed in the choices given. The choice stating "All employees in the U.S." is overly broad, as certain employees do not fall under OSHA regulations, such as those in specific agricultural roles or self-employed individuals.

Overall, the best answer
