Which of the following is suitable for transporting fish a long distance?

The option that is suitable for transporting fish a long distance is a refrigerated ship. This is because fish is a perishable commodity, and it needs to be kept fresh to prevent spoilage during transportation. A refrigerated ship has special cooling equipment that can maintain a low temperature in its cargo hold, which helps to preserve the freshness of the fish. This makes it an ideal option for transporting fish over long distances. The other options, such as tramp, cargo liner, tanker, and barge, may not have the necessary equipment or facilities to keep the fish fresh during transportation.
