A) Separation of butter from curd.
B) Separation of salt from sea water.
C) Sprinkling water on a dusty street before sweeping.
D) Separation of grain seeds from their stalks.
Correct Answer: C
Solution :

It is a common experience that after rain, the sky looks clear and brighter. This is because the dust particles settle down due to loading by rain drops.
