You are making a telephone call ship-to-shore using the VHF-FM service. You can tell that the working channel is busy if you hear _______________.
AI Explanation
The correct answer is D) All of the above.
When making a telephone call from a ship to shore using the VHF-FM service, you can tell that the working channel is busy if you hear any of the following: speech, signaling tones, or a busy signal. This is because the VHF-FM service is a shared communication channel, and if it is already in use, you will hear these indications that the channel is occupied.
The other options are incorrect because they do not fully encompass the different ways you can detect a busy working channel. Hearing speech or signaling tones would indicate that the channel is in use, while a busy signal would indicate that the channel is unavailable for your call.
