Answer 1

Answer:

III. Colloids settle down when left undisturbed is false statement about colloids

Particles in colloid is very small compare to that of the suspension. This makes the colloids more stable than suspension.  Because of the larger size of particles they settle down when suspension is left undisturbed. While in the case of colloid they do not settle as the particles are very small.
