Which statement is correct regarding the classification of a truck?

Answer: C — truck is primarily for transporting property

The classification of a truck is primarily defined by its intended use, which is the transportation of property. Trucks are designed and equipped to carry goods and cargo, making them distinct from vehicles specifically for passenger transport. This functional role encompasses a wide variety of vehicles, from light-duty pickup trucks to heavy-duty freight trucks, all serving the primary purpose of transporting materials rather than people. The other options do not accurately reflect the characteristics of trucks. For example, trucks can vary significantly in size, so labeling them as always larger is misleading. Additionally, trucks can indeed be equipped to tow trailers, which is common in many transportation scenarios. Thus, the focus on a truck's primary purpose as a vehicle for transporting property is the key aspect that makes this statement correct.
