Which of the following describes a "dry-van" container?

A "dry-van" container is specifically designed to provide a weather-tight, enclosed space for cargo. This type of container protects the contents from the external environment, such as rain, snow, and wind, ensuring that the goods inside are secure and unaffected by weather conditions. The emphasis on being weather-tight is crucial for transporting various types of cargo that must not come into contact with moisture or other elements found outdoors.

The other descriptions do not accurately represent a dry-van container. For instance, a container that is open to the environment lacks the necessary protections and security that characterize a dry-van container. Similarly, containers designed for live animals or those intended for liquid transport have specialized features tailored to their specific cargo requirements and therefore do not fit the definition of a dry-van container.
