In a colloidal solution________

 
the size of a colloidal particle lies roughly between 0.1 nm to 1 nm.
the particles have a tendency to settle when the solution is left standing.
the particles pass through ultrafilter papers and animal and vegetable membranes.
the dispersed phase is uniformly distributed in the dispersion medium
Please type your answer before submitting.

Maam, on module pg 67, where the table of differenciation of colloids,truesolutions and suspensions is given which states that the nature of the colloidal solutions is heterogeneous. If so then how is D the correct option if it states that "the dispersed phase is uniformly distributed in the dispersion medium" please clarify waiting for your reply....
