What is the typical range for the $CMC$ (Critical Micelle Concentration) of soap in aqueous solution?

• A
  $10^{-4} \text{ to } 10^{-3} \text{ mol L}^{-1}$
• B
  $10^{-2} \text{ to } 10^{-1} \text{ mol L}^{-1}$
• C
  $10^{-6} \text{ to } 10^{-5} \text{ mol L}^{-1}$
• D
  $10^{-9} \text{ to } 10^{-8} \text{ mol L}^{-1}$
