Which wall is likely to be a non-load-bearing wall?

A partition wall is likely to be a non-load-bearing wall because its primary purpose is to divide interior spaces within a building rather than to support any structural loads. These walls do not bear the weight of the building above them and can often be moved or changed without affecting the overall integrity of the structure.

In contrast, shear walls are specifically designed to support lateral loads, providing stability against wind and seismic activities, and thus are load-bearing. Load-bearing walls are crucial as they support the weight of elements like floors and roofs above them. Basement walls also serve a structural role by holding up the building and resisting soil pressures. Since the partition wall's function is purely for spatial division, it stands out as the clear candidate for being non-load-bearing.
