What is the international distress frequency for radiotelephones?

A 2738 kHz
B 500 kHz
C 2182 kHz
D 1347 kHz
AI Explanation

The correct answer is C) 2182 kHz. The international distress frequency for radiotelephones is 2182 kHz. This frequency is designated by international maritime regulations for emergency communications, including distress calls, from ships and other vessels. It is the primary frequency used for voice communications in the global maritime distress and safety system (GMDSS). The other answer choices are incorrect because: A) 2738 kHz is not the international distress frequency, B) 500 kHz is the former international distress frequency for Morse code, and D) 1347 kHz is not a recognized maritime distress frequency.
