Answer 2

(A)

The range of particle size in a colloidal solution is 1 nanometre to 1 micrometer. colloidal solution is a heterogeneous mixture, they are very small & can pass through filter paper

Colloidal particles are larger than simple molecules but small enough to remain suspended. Their range of diameters is between 1 and 1000 nm (10−5 to 10−7cm).
