The signs of water damage that are outlined in the first choice—discoloration, warping, musty odors, and peeling paint or wallpaper—are essential indicators that help identify the presence of moisture issues in a building.

Discoloration often manifests as stains on walls and ceilings, which can be attributed to water intrusion. When moisture accumulates, it can cause materials such as drywall and plaster to swell and distort, leading to warping. Musty odors are a clear sign of mold growth, often associated with excessive moisture in an environment. Peeling paint or wallpaper indicates that the substrate underneath is wet, causing the adhesive to fail and leading to these materials losing their bond and separating from the surface.

Together, these signs provide a comprehensive view of potential water damage and are critical for early detection and intervention, which can prevent more extensive damage and costly repairs. The other options may indicate structural issues or other problems, but they do not directly present as common signs specifically tied to water damage.
