Question 367 Deck Safety

The correct answer is B) green. The color of the signal flare sent up by a submarine indicating that a torpedo has been fired in a training exercise is green. This is because the green signal flare is the standard color used to indicate that a training exercise is in progress, as opposed to an actual emergency situation. The green color helps distinguish the training exercise from a real-world torpedo firing, which would typically be indicated by a different color flare. The other answer choices are incorrect because white, red, and yellow flares are not the standard colors used to signal a training exercise torpedo firing from a submarine.
