Cargo carried by aircraft:

**The reasoning** This is a straightforward **vocabulary and classification question** about modes of transportation. Each transportation method has a specific name for the cargo it carries: - **Aircraft** (planes) carry goods → **Air freight** - Ships carry goods → **Sea freight** - Trains carry goods → **Rail freight** - Pipelines carry liquids/gases → **Pipeline transport** The question asks what cargo carried *by aircraft* is called. Aircraft use air as their medium of transport, so goods transported this way are called **air freight**. **Why the wrong options tempt you** - **A (Sea freight)** might catch you if you're thinking generally about "freight" but forget the transport mode specified - **B (Rail freight)** could trip you if you're not carefully reading "aircraft" - **D (Pipelines)** doesn't even carry packaged cargo like aircraft do—it's for liquids and gases only **Quick takeaway** Match the transport method to its freight name: aircraft = **air** freight, ships = **sea** freight, trains = **rail** freight. The vehicle tells you the answer.
