Quizplus · Accepted Answer

Colloidal particles typically range in size from 1-1000 nm, which is larger than option A. However, they do scatter light, which is the defining characteristic of a colloidal solution. Option C is a combination of both A and B, but since A is not true, it is not the best choice. Option D is incorrect as well, as colloidal particles do exist and have distinct properties.
