Question 11 Deck Safety

The correct answer is D) Any of the above. Distress signals can include smoke signals, red flares, and sound signals. The U.S. Coast Guard regulations specify that distress signals can take various forms, including visual signals like smoke and flares, as well as audible signals like horns or whistles. All of the listed options (A, B, and C) are considered valid distress signals that can be used to indicate an emergency situation at sea. The other options are incorrect because they each only mention one type of distress signal, when in reality, distress signals can encompass multiple modalities to increase the chances of being detected by rescuers.
