The correct option is C 2 and 3 only

Statement 2 is correct: The separation of cream from milk is due to centrifugal force.

Statement 3 is correct: This is the reason why the moon lacks atmosphere. The escape velocity is lesser on the moon than on earth and hence most of the gas molecules escape from the moon’s surface.
