Question 357 Deck Safety

The correct answer is C) red. Red is the color used for rockets, shells, or rocket parachute flares to indicate that a vessel is in distress and requires immediate assistance. This is in accordance with international maritime regulations, which specify the use of red distress signals to alert other vessels and authorities of an emergency situation. The other color options, white, green, and yellow, are not the standard colors used for emergency distress signals at sea.
