The Correct Option is B

Solution and Explanation

Micelles consist of a hydrophobic core and a hydrophilic surface, enabling the solubilization of poorly water-soluble drugs. They form spontaneously in aqueous solutions when surfactants reach the critical micelle concentration (CMC). Micelles enhance drug absorption and protect sensitive drugs from degradation.
