I gave my students this multiple choice question: Which is the best example of evaporation?

Only one answer is correct among these 4 choices:
- raindrops freezing
- an ice cube melting
- a puddle drying in the sun
- a sponge soaking up water

Could you tell me which one is correct?

a puddle drying in the sun
