The correct option is clouds.
To reach this option we have to take into account the water cycle which is the process of transformation and circulation of water on earth. In this sense, the water cycle consists in the transfer of water from one place to another, changing its physical state. The water cycle is divided into different phases:
The water cycle begins with evaporation. Evaporation occurs when the sun heats the surface of the waters of rivers, lakes, seas and oceans. The water, then, is transformed into steam and goes up into the atmosphere, where the next phase will take place: condensation.
<em>During this phase, the water vapor that has risen into the atmosphere thanks to evaporation, concentrates in droplets that will form clouds and haze.</em>
