The correct answer is D) In no case. According to Coast Guard regulations, cargo from a tank barge must not pass through or over the towing vessel under any circumstances. This is a safety requirement to prevent the potential spill or release of hazardous cargo onto the towing vessel. The regulations do not allow for any exceptions to this rule, even with permission from the person in charge of the towing vessel or the shore facility. The other answer choices suggesting otherwise are incorrect, as they would violate the applicable regulations for the safe transfer of cargo from a tank barge.
