Answer» Correct Answer - B At a certain concentration surfactant molecules start to ggregate and form micelle, the concentration is called critical micellisation concentration (CMC). Aggregation of surfactant molecules (ions, `RCO O^(-)`) micelle formation cause effective fall in number of free ions to conduct electricity, thus, conductivity decreases at CMC.
