If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

(A) The stability of colloidal solutions is primarily due to the Brownian movement of particles.Brownian movement is caused by the continuous bombardment of colloidal particles by the molecules of the dispersion medium.This random motion counters the force of gravity,preventing the particles from settling down,thereby ensuring the stability of the colloidal system.
