Solution
The correct option is A Blood
Tyndall effect is the phenomenon of scattering of a beam of light by a medium containing small suspended particles.
This effect was first observed by faraday later studied in detail by Tyndall.
This effect arises due to scattering of light by colloidal particles in all directions . Scattering of light illuminates the path of beam in the colloidal dispersion.
It is used to distinguish between a colloidal and a true solution.
True solution does not show Tyndall effect but colloidal solution shows.
Since, blood is a colloid, tyndall effect is observed when a beam of light is passed through it. Hence, option (a) is correct.
Water, copper sulphate and brine are true solution so they does scatter light while passing through it.
