Question 173 Deck Safety

The correct answer is B) IN DEE AH. The International Radiotelephony Spelling Alphabet, also known as the NATO phonetic alphabet, is the standard way to pronounce letters over the radio to avoid confusion. According to this standard, the letter "I" is pronounced as "IN DEE AH" when spoken on the radiotelephone. The other options are incorrect because they do not follow the established radiotelephony spelling alphabet. A) I VAN HO and C) IN DEE GO are not the standardized pronunciations, while D) I EE is simply incorrect.
