Solution
The correct option is B colloidal The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible. The amount of scattering depends on the frequency of the light and density of the particles. Milk is a colloid that exhibits the Tyndall effect.
