Solution
The correct option is C Vinegar
The Tyndall effect is the phenomenon in which the particles in a colloid scatter the beams of light that are directed at them. This effect is exhibited by all colloidal solutions and some very fine suspensions.
Therefore, it can be used to verify if a given solution is a colloid. (The intensity of scattered light depends on the density of the colloidal particles as well as the frequency of the incident light.)
In case of true solutions, the particles are so fine that they cannot scatter the incident light, hence they do not show tyndall effect.
Vinegar is a solution which has acetic acid dissolved in water.
