The critical micelle concentration (CMC) of a soap solution is $5 \times 10^{-4} \mathrm{~mol} \mathrm{~L}^{-1}$. Identify the correct statements about this solution.
I. The micelle is stable if the soap solution concentration is $10^{-7} \mathrm{~mol} \mathrm{~L}^{-1}$.
II. The micelle is stable if the soap solution concentration is higher than $5 \times 10^{-4} \mathrm{~mol} \mathrm{~L}^{-1}$.
III. Micelles are also known as associated colloids.
