The rail car type used for pressurized contents is the:

Explanation:
Pressurized contents require a rail car designed to withstand internal pressure. A pressure tank car has a strong, thick-walled shell and pressure-relief devices to safely contain gases or vapors at higher-than-atmospheric pressures. It’s specifically built for pressurized cargo, unlike general service tank cars (non-pressurized liquids), cryogenic tank cars (extremely cold temps), or insulated tank cars (primarily for temperature control, not pressure). This is why the correct choice is the pressure tank car.
