Suspension and Colloidal Solution

Assertion (A) : When CO_2 is passed through lime water the solution turns milky but with an excess of CO_2 the solution becomes clear again . Reason (R) : Excess CO_2 changes the suspension to a colloidal solution .

The size of particles in suspension , true solution and colloidal solution varies in the order :
