Which of the following best distinguishes a true aqueous solution from a suspension with respect to the size and behavior of the dispersed species?
(a) The dispersed species in a solution strongly scatter visible light, producing the Tyndall effect, whereas those in a suspension do not appreciably scatter light.
(b) The dispersed species in a solution consist of individual ions or molecules small enough to pass through ordinary filter paper, whereas those in a suspension are larger aggregates that are retained by the paper.
(c) The dispersed species in a solution are lighter than water and therefore remain indefinitely dispersed, whereas those in a suspension are heavier and rapidly settle to the bottom.
(d) The dispersed species in a solution are large enough to be retained by ordinary filter paper, whereas those in a suspension are small enough to pass through the paper.
