The correct answer is A) automatically when the raft is inflated. The lights on the outside of the canopy of an inflatable life raft are designed to activate automatically when the raft is inflated. This is a safety feature that helps the raft be visible in the water, which is crucial for search and rescue operations. The inflation of the raft triggers a mechanism that turns on the lights, ensuring they illuminate without any manual intervention. The other answer choices are incorrect because the lights do not operate by a light sensor (B), by a switch at each light (C), or by turning the globe clockwise (D). These methods would require the user to take additional actions to activate the lights, which goes against the automatic safety design of the life raft's lighting system.
