The correct option is B Water drops appearing on the outer surface of a cool water bottle.
Condensation is the change in the state of matter from the gas into liquid droplets. Condensation is an important part of the water cycle. It is the opposite of evaporation.
Examples of Condensation: Having a cold soda on a hot day, the can "sweats." Water molecules in the air as a vapour hit the colder surface of the can and turn into liquid water.
