Which one of the following is not a form of condensation?

Condensation is the process where water vapor changes into liquid or solid form when air reaches its dew point. Common forms of condensation include dew, white frost, fog, and mist [2]. Dew forms when vapor condenses into liquid droplets on cold surfaces above freezing [1]. White frost occurs when condensation (specifically deposition) happens below the freezing point, creating ice crystals [3]. Fog consists of minute water droplets or ice crystals suspended in the air near the ground [5]. In contrast, sleet is a form of precipitation rather than a primary form of condensation [4]. Sleet consists of frozen raindrops or refrozen melted snow that falls as small ice pellets when a subfreezing layer of air exists near the ground [5]. While dew, fog, and frost are categorized as condensation products occurring at or near the surface, sleet is classified as frozen precipitation [5].
