which of the following options are correct?

Micelle formation some substances at low concentration behaves as a normal electrolytes but at higher concentration exhibit colloidal behaviour due to formation of micelles.CMC (Critical Micelle Concentration) the concentration above which it behaves as a micelle known as critical micelle concentration (CMC).e.g. soap solution in aqueous solution above particular concentration (called CMC = 10-4 - 103 mol L-1) forms soap micelles.on dilution soap solution behaves as a normal electrolyte and after adding excess of water, intermolecular force of attraction between the soap particles decreases and soap solution micelles may revert to individual ions.
