Assertion (A) An ordinary filter paper impregnated with collodion solution stops the flow of colloidal particles. Reason (R) Pore size of the filter paper becomes more than the size of colloidal particle. (a)Assertion and reason both are correct and the reason is correct explanation of assertion. (b)Assertion and reason both are correct but reason does not explain assertion. (c)Assertion is correct, but reason is incorrect. (d)Both assertion and reason are incorrect.

Filter paper can be used to separate the components of a suspension. Why?
