Solution

The correct option is A Glycerine
As the coefficient of viscosity of glycerin is greater than that of water and kerosene, therefore the relative motion between adjacent layers of glycerin is more strongly opposed compared to water and kerosene. Hence, glycerin comes to rest earlier than water and kerosene.
