Answer & Explanation
The correct answer is Option A: 500 kHz, 2182 kHz, and 156.8 MHz.
The frequency 500 kHz (radiotelegraphy), 2182 kHz (radiotelephony), and 156.8 MHz (VHF Channel 16) are the designated international distress and calling frequencies. While technology has shifted toward DSC, these remain the core frequencies for distress alerting.
