70% to pass

The light on a life jacket must be replaced _______________.

A when it is no longer serviceable
B each year after installation
C when the power source is replaced
D every six months
AI Explanation

The correct answer is A) when it is no longer serviceable. According to US Coast Guard regulations, the light on a life jacket must be replaced when it is no longer serviceable, meaning when the light is no longer functioning properly. This is the only requirement - the light does not need to be replaced on a set schedule like annually or every six months, nor does it need to be replaced when the power source is replaced. As long as the light is still working, it can remain on the life jacket. The other options are incorrect because they do not accurately reflect the Coast Guard's requirements for maintaining the light on a life jacket.
