Question 374 Deck Safety

The correct answer is D) black. When a submarine indicates that a torpedo has been fired during a training exercise, it will release a black smoke float. This is in accordance with established procedures and regulations for signaling the firing of a torpedo from a submarine. The black smoke is designed to be clearly visible and easily identifiable as an indication of a torpedo firing, which is a critical safety signal during training exercises. The other answer choices (red, yellow, orange) do not correspond to the standard signaling protocols for a fired torpedo and would not be the correct color of smoke released in this scenario.
