Answer:
(B) Between true solution and suspension.
Explanation:
The dimension of colloid particles is in between of solution and suspension.
A colloid always forms a heterogeneous mixture. The particles of the colloid can be solid, liquid or gas which is dispersed in the medium. The dispersed particles are not larger than the suspension and due to this reason, the particles do not settle down.
Fog and mist are examples of colloids where the dispersed phase is liquid and the dispersion medium is solid. Their size ranges from 1 to 1000 nm.
