Which situation would most likely result in freezing precipitation?

Freezing precipitation occurs when liquid rain falls into a layer of air that is at or below freezing temperature (32°F or 0°C). In this scenario, rain droplets that are originally formed in warmer air (above 32°F) descend into a colder air mass where temperatures are at or below freezing. As these droplets make contact with surfaces that are also at or below freezing, they can freeze upon impact, leading to the formation of ice.

This situation is most conducive to freezing rain because the rain starts as liquid in the warmer layer, and as it travels downward towards the colder layer, it does not have enough time to freeze before reaching the ground. Consequently, when these droplets hit the ground or other surfaces, they freeze instantly, creating a layer of ice.

This phenomenon is often seen in winter weather scenarios where a warm front passes over colder air, leading to various types of winter precipitation, including freezing rain. The other options describe situations that do not meet the conditions necessary for freezing precipitation. For instance, rain falling from cold air into warmer air would not freeze; instead, it would typically remain liquid.
