Detailed Solution

A is a suspension. B and D are colloids. C is a solution

On leaving undisturbed, the particles of the substance settle down in A, so it is suspension.

Path of a beam of light passing through it and light is invisible in C. so it is a solution.

Path of a beam of light passing through B and D was visible in B and D.

On leaving undisturbed, the particles of the substance not settle down in B and D. So, B and D are colloids.
