Solution

The correct option is D Viscosity
Rain drops fall with terminal velocity due to the viscosity of air. Terminal velocity is speed of the object when net force on the object is zero. In case of rain drops due to mass of drop weight acts in downward direction and viscous force of air acts in upward direction.
