Which of the following best describes the cause of cabin fog during rapid decompression?

During rapid decompression, the cabin air expands and cools quickly. As the temperature drops, water vapor in the air reaches its dew point and condenses into tiny droplets, creating visible fog in the cabin. Humidity contributes more moisture, but the fog forms mainly because that moisture condenses when the air cools rapidly. Smoke from equipment or dust from vents would present differently and aren’t the primary cause of the fog.
