The provisions allow local authorities to require alarm operators to obtain licenses or permits. This demonstrates what about local power?

• A. Local authorities retain police power by ordinance
• B. Local authorities have no power
• C. Only state can regulate alarm companies
• D. Local authorities can suspend licensing

Answer: (A)

Local governments have the authority to regulate public safety within their borders, and they do this through ordinances. When they can require alarm operators to obtain licenses or permits, it shows they are exercising that local police power to govern activities that affect residents’ safety and welfare. This power is granted by the state to localities and used via local rules, not by the state alone dictating every detail.

So the best explanation is that local authorities retain police power by ordinance. The other ideas don’t fit because localities do have power to regulate locally, regulation isn’t limited to the state, and licensing is just one way local control is exercised (suspension or revocation can occur under an ordinance, but the core point is the authority to require licensing as an exercise of police power).
