Final answer:
Hazardous materials cannot be carried on a bus due to their potential risks, while live animals, furniture, and clothing may be permitted based on bus company policies and safety considerations.
Step-by-step explanation:
Among the options provided, hazardous materials are typically the type of cargo that can never be carried on a passenger bus. Modern transportation regulations strictly control the movement of hazardous materials due to the potential risks to passengers and the public. There are specific vehicles and cargo holds designed to safely transport hazardous substances, which include explosive, flammable, toxic, or corrosive materials, and these are often subject to rigorous safety standards.
While live animals, furniture, and clothing may have some restrictions depending on the bus company's policy, these items do not generally pose the same level of inherent danger as hazardous materials and thus can sometimes be transported by bus, subject to space, safety, and welfare considerations.
