Final answer:
The Fair Labor Standards Act is the best example of a regulation as it establishes specific rules for labor standards that must be followed.
Step-by-step explanation:
The best example of a regulation is b) Fair Labor Standards Act. This act, listed in Table 14.4, represents a clear instance of labor market regulations set by the government to establish minimum wage, overtime pay eligibility, recordkeeping, and child labor standards affecting full-time and part-time workers in the private sector and in Federal, State, and local governments. Regulations such as the Fair Labor Standards Act create enforceable rules that must be followed, while items like the Civil Rights Act of 1964, although highly significant as legislation that outlaws discrimination, serve a slightly different purpose as foundational civil rights legislation.
