The correct answer is D) All of the above. The operator of an uninspected vessel is required to assist people affected by an accident, as long as they can do so without harming persons onboard, further damaging the other vessel, or serious danger to their own vessel. This is outlined in the Code of Federal Regulations (CFR) for the U.S. Coast Guard. The other options are incorrect because the operator is not required to assist if doing so would put their own vessel or crew at serious risk. The regulation requires the operator to provide assistance, but not at the expense of their own safety or that of their vessel.
