Cargo tanks are primarily designed for the safe transport of liquids and gases. They are specifically constructed as bulk packaging that is permanently attached to a vehicle, enabling efficient and secure movement of bulk quantities of these substances.

The design of cargo tanks ensures that the materials being transported are contained securely, while also adhering to necessary regulations regarding hazardous materials. This is vital for ensuring safety during transit, especially when dealing with potentially dangerous goods, as improper handling can lead to spills or leaks, posing risks to public safety and the environment.

The other options relate to different types of materials and storage methods. Solid waste materials are typically handled through different waste management systems, while permanent storage at facilities would involve containers or tanks designed for holding materials on-site rather than transporting them. Distributing dry goods pertains to a different category entirely, focusing on non-liquid products that do not require the specialized tank design for transport. Thus, cargo tanks' primary function as bulk packaging for liquids and gases solidifies their specific and essential role in hazardous material transport.
