A liquefied flammable vessel primarily transports gases that can easily ignite and support combustion, typically known as liquefied petroleum gases (LPG). Propane and butane are two common examples of gases that fall into this category. These gases are stored under pressure in a liquid state, allowing for efficient transport and storage. Upon release from their pressurized containers, they vaporize and can mix with air, creating a flammable mixture.

In contrast, the other choices listed do not involve the transportation of flammable gases. Oxygen, although essential for combustion, is not classified as a flammable gas itself. Liquefied nitrogen is used primarily in industrial applications and is an inert gas that does not support ignition. Lastly, carbon dioxide, while it has uses in fire extinguishing and in various industrial processes, is also not flammable and does not support combustion.

This understanding of the characteristics of the gases and their properties clarifies why the option mentioning propane and butane is the correct answer in the context of liquefied flammable vessels.
