The correct statement(s) related to colloids is

(A) The process of precipitating colloidal solution is called coagulation. Hence false. 
(B) For colloidal solutions concentration is very small due to very large molar mass and hence their colligative properties are very small as compared to true solutions $\therefore \Delta T_f$  is lesser for colloidal solution. Hence false.
(C) At CMC surfactant from micelles. Hence true
(D) Micelles and macromolecular colloids are two different types of colloids. Hence false.
