Question 171 Deck Safety

The correct answer is C) OSS CAH. The International Radiotelephony Spelling Alphabet, also known as the NATO phonetic alphabet, is the standard way of pronouncing letters over the radio to ensure clarity and avoid confusion. According to this standard, the letter "O" is pronounced as "OSS CAH" when spoken on the radiotelephone. The other options are incorrect because they do not follow the standard pronunciation laid out in the International Radiotelephony Spelling Alphabet. For example, "OCK TOW BER" is not the proper way to pronounce the letter "O", and the other choices also deviate from the established standard.
