The Correct Option is C

Solution and Explanation

Step 1: In colloids, particles are very small and remain uniformly dispersed; they do not settle on standing.
Step 2: In suspensions, particles are larger and tend to settle down when left undisturbed.
Step 3: Therefore, the statement in option (C) is incorrect for colloids.
