Answer:
Imagery
Explanation:
Imagery describes a scene using a person's senses, such as sight, hearing, touch, smell, or taste, sometimes a mix of both. This sentence describes how the snow fell onto someone's face in a vivid way.
Personification - It doesn't say that the crisp snow did anything human, it says it melted into a small puddle.
Symbol - The crisp snow doesn't represent any event, emotion, etc. It's simply a description.
Connotation - I think we all know that this isn't the right answer
