Who issues the regulations governing the frequencies of the bridge-to-bridge radiotelephone?

Correct Answer: Option D — Federal Communications Commission

The Federal Communications Commission (FCC) holds the regulatory authority over radio frequency allocations and technical standards for maritime communications. While the USCG enforces the Bridge-to-Bridge Act, the FCC governs the technical operation, licensing, and frequency assignments for all radiotelephone equipment used on vessels within US jurisdiction.
