Solution

The correct option is A
tyndall effect

When rays of light pass through a colloidal solution or suspension, the tiny particles get illuminated due to scattering. Because of this, the path of light is made visible. This phenomenon is called tyndall effect. The intensity of scattering depends on the size of the particles in the colloid.
