C Correct answer
Explanation

Mist forms when warm, moist air cools rapidly, causing water vapor to condense into tiny suspended water droplets near the ground. This typically happens on clear, calm nights when the ground cools by radiation, cooling the air above it to its dew point. Dry ice and carbon monoxide are not involved in natural mist formation, and ice at low temperatures would be frost, not mist.
