Identify the correct statements from the following :
$I$. Sulphur sol is an example of a multimolecular colloid.
$II$. Tyndall effect is observed when the diameter of the dispersed particles is not much smaller than the wavelength of the light used.
$III$. The process of removing a dissolved substance from a colloidal solution by means of diffusion through a suitable membrane is called peptisation.
$IV$. Eosin,gelatin are examples of negatively charged sols.

Match List-$I$ and List-$II$.

List-$I$	List-$II$
$A$. Osmosis	$I$. Solvent molecules pass through semi permeable membrane towards solvent side.
$B$. Reverse osmosis	$II$. Movement of charged colloidal particles under the influence of applied electric potential towards oppositely charged electrodes.
