Which sign could indicate depressurization?

Explanation:
When cabin pressure drops, the air expands and cools. The humidity in that air then condenses on cooler surfaces, producing visible mist or fog inside the cabin. That makes mist forming in the cabin the clear, observable sign of depressurization. Calm breathing and passengers sleeping aren’t indicators of a pressure loss, and while a rapid pressure drop can cause liquids to boil at lower temperatures, that isn’t a typical or reliable cue for depressurization in the cabin.
