Solution

The correct option is B
A translucent solution is formed.

Egg white in water forms a colloidal solution. When we pass a beam of light through a colloidal solution, the path of the light becomes visible when seen from a direction at right angle to that of the incident light. Usually, the particles of size in the range of $10^{- 9} m$ to $10^{- 6} m$ scatter the visible light. This scattering of light by particles in a colloid is known as Tyndall effect.
