Which frequencies and modes are allocated for distress alerting in GMDSS?

AI Explanation
The correct answer is A) Channel 70 DSC plus six (6) frequencies. In the Global Maritime Distress and Safety System (GMDSS), the frequencies and modes allocated for distress alerting are: - Channel 70 for Digital Selective Calling (DSC) - Six (6) dedicated distress and safety frequencies for voice and/or digital communications, including 2182 kHz, 4125 kHz, 6215 kHz, 8291 kHz, 12290 kHz, and 16420 kHz. The other options are incorrect because they do not fully encompass the complete set of GMDSS distress alerting frequencies and modes as specified by international regulations.
