Answer: The correct answer would be B. exosphere
Step-by-step explanation:
Water cycle refers to the cyclic movement of water in the biosphere. The water moves through various spheres and transforms in various physical states.
The water from hydrosphere (water bodies) evaporates and travel into atmosphere in the form of water vapours.
The water vapours condense and form clouds which then precipitate in the form of rain, snowfall, moist, et cetera.
Living organisms also contribute in water cycle through the process of transpiration and urination.
Exosphere is the outermost thin layer surrounding a planets, natural satellites, et cetera. It does not participate in water cycle.
