For an ionic micelle-forming surfactant near its critical micelle concentration (CMC), which of the following graphs rightly show the variation of mentioned properties with concentration of the surfactant

A concentration approaches concentration molar conductivity decreases steeply, surface tension keeps on decreasing and reaches a constant value, osmotic pressure keeps on increasing and reaches a steady value, detergency keeps on increasing and reaches the highest value.

$C=CMC,(d^{3}F/d{C}_t^3)=0$
