Which of the following is among the functions counties may perform?

• A. Public Transportation
• B. Tax collection
• C. International trade regulation
• D. Issuing passports

Answer: (A)

Local governments like counties are empowered to provide services that directly affect residents’ daily lives. Public transportation is a classic county-level function because it involves planning, funding, and operating services that serve the local community, support mobility, and stimulate local economy. This kind of service falls squarely within what counties typically handle to meet local needs.

International trade regulation and issuing passports are clearly federal responsibilities, not something a county would manage. Tax collection is indeed a governmental function, but the question focuses on the type of direct public service counties commonly provide, and public transportation best exemplifies that county-level service.
