Which of the following describes the term "Air cargo"?

The term "Air cargo" specifically refers to goods that are transported by cargo planes. This mode of transportation is crucial for moving freight quickly over long distances, benefiting industries that require prompt delivery of goods or those that deal with time-sensitive shipments. Air cargo encompasses a wide range of items, from small packages to large freight, and it plays a significant role in global trade and logistics.

When considering the other options, goods shipped via ship or rail does not fit the definition since it refers to different modes of transportation entirely. Goods that are stored in warehouses, while related to logistics, does not imply any specific method of transportation, and therefore, is not directly associated with air cargo. Lastly, goods that do not require special handling does not accurately represent air cargo, as many air cargo shipments may require special handling due to their nature or sensitivity. This underlines that air cargo encompasses specific logistics and transportation methods rather than general storage or other modalities of transport.
