Which type of wall is described as fire rated and is built to withstand collapse for 2-4 hours?

The correct answer is the fire-wall. A fire-wall is specifically designed to prevent the spread of fire between structures or different sections of the same building. It is constructed to withstand fire exposure for a specified duration, typically between 2 to 4 hours, which is crucial for providing a safety barrier that protects occupants and property. These walls are built with materials that have a high fire-resistance rating and are essential in fire prevention and control strategies within buildings.

In contrast, load-bearing walls support the structural weight of the building but are not specifically designed with prolonged fire resistance in mind. Non-bearing walls do not support any weight and primarily serve as partitions; they might not possess any fire-rated qualities. Partition walls are generally lightweight walls that divide spaces within a building and are not built to be fire-rated. Therefore, a fire-wall is the only option described that meets the criteria of being fire rated and capable of withstanding structural collapse for the specified duration.
