The common characteristic of suspension and colloidal solution is:

A
Both are heterogeneous.
B
The particles of both can pass through filter paper.
C
The particles of both are visible to naked eye.
✓
The particles do not settle at the bottom under gravity.

✓

Answer

Correct option: D.

The particles do not settle at the bottom under gravity.

The colloidal particles are smaller and not heavy. They always remain in a state of zig$-$zag motion, called Brownian movement, which counters the force of gravity acting on colloidal particles and hence, helps in providing stability to colloidal sols by not allowing them to settle down.
