Question 163 Deck Safety

The correct answer is B) use English language. When transmitting a distress message by radiotelephone, the international regulation is to use the English language. This is specified in the International Telecommunication Union (ITU) Radio Regulations, which are the global standards for radio communications. Using English ensures the distress message can be understood by the widest possible audience, which is critical during an emergency situation. The other answer choices are incorrect because: A) the International Code is used for distress signaling by visual means, not radiotelephone; C) "Interco" is not a recognized prefix for distress calls; and D) the radio alarm signal is a separate procedure, not part of the distress message transmission.
