Final answer:
Cold, dry air is least likely to have precipitation because cold air has a lower capacity to hold moisture compared to warm air.
Step-by-step explanation:
The air condition that would be least likely to have precipitation is C. cold, dry air. This is because cold air has a lower capacity to hold moisture compared to warm air. When air cools, its water vapor condenses and forms clouds, which eventually leads to precipitation. Therefore, cold air with less moisture would be less likely to produce precipitation.
