Solution
The correct option is B Evaporation Puddle formed by rain drops get heat energy from bright sunshine. When we supply heat energy to the matter it changes its state.
Water is initially in liquid state in puddle but when we supply heat energy it changes to gaseous state (vapour).
The phenomenon of change of a liquid into vapours is called evaporation.
