I gave my students this multiple choice question: Which is an example of water condensing? 1.

Only one answer is correct among these 4 choices:
- puddle disappearing on a hot summer afternoon
- Sweat forming on your forehead after you do a lot of exercise
- Ice cubes melting when you put them out in the sun
- Dew forming on plants during a cold night

Could you tell me which one is correct?
