(A) Zeolites can act as molecular sieves allowing smaller molecules and trapping larger molecules. So, (A) - (c). (B) Ethanol peptises cellulose nitrate to give so called "collodion". Thus, (B) - (e). (C) A micelle is a cluster of aggregated particles formed by associated colloids in solution. Sodium stearate [(a)] and cetyl trimethyl ammonium bromide [(f)] are examples of micelles. So, (C) - (a), (f). (D) Digestion of fat in the intestine is aided by emulsification [(b)]. The disinfectant "dettol" gives emulsion when mixed with water. Thus, (D) - (b), (d).
