C Correct answer
Explanation

When a cold glass sits in warm air, water vapor in the air contacts the cold surface and condenses into liquid droplets on the outside. This is condensation - the same process that causes dew on grass. The water doesn't freeze, change color, or evaporate; droplets form on the exterior due to temperature difference.
