The following are some statements about micellesI) These are formed as aggregated particles when soap is applied at lower concentrationsII) The tail part of it dissolves the grease deposit or dirt.III)  Hydrocarbon chain of soap micelle is hydrophillic end and its anion part is hydrophobic end.The correct combination is

Soaps and detergents behave like true solutions at low concentrations but form colloids aboveCritical micelle concentration(CMC) which is 10-4M-10-3M due to association is sodium stearate(soap) part is Hydrophobic(nonpolar) part(tail) part is Hydrophilic(polar) part(head)At low concentration;                                ions present on surface with groups in water and   chains staying awayand remain at the surfaceAt or above CMC the polar part (or) the anion part ( )  are pulled into the bulk  where they aggregate to form spherical shapewith the   part(non polar) towards the centre of the sphere and part remaining outward on the surface of the sphereMicelles are formed due to association above CMC ;   I is falseThe Hydrophobic part dissolves the grease deposit ;   II is trueHydrocarbon chain is Hydrophobic , anionic part is hydrophilic;   III is false
