  1. Evaporation, condensation, precipitation

  2. Condensation, precipitation, evaporation

  3. Evaporation, precipitation, condensation

  4. Precipitation, evaporation, condensation

Show answer
Correct Option: A
Explanation:
Answer is option A i.e. "Evaporation, condensation, precipitation"
There are 3 main stages involved in water cycle i.e. evaporation, condensation, precipitation and runoff. The water cycle starts with evaporation followed by condensation where water vapor converts int liquid water and finally precipitation where liquid water falls from sky in form of rains, snow, hail, etc.
