A fire-rated door is designed to prevent the spread of fire and smoke within a building for a certain amount of time. To achieve this, a fire-rated door must meet certain requirements including being self-closing, labeled with a fire rating, and having a solid core construction. These features are crucial in containing a fire and minimizing its damage.

Option D, minimum height of 2.0 meters, is not a requirement for a fire-rated door. The height of a door does not affect its ability to prevent the spread of fire and smoke. This option may be included in building codes or regulations regarding accessibility, but it is not directly related to the fire safety of the door.
