- Bcolloidal structure of soap in water is completely disturbed.
- Cthe hydrophobic part of soap is not able to take away grease.

Correct answer
D. the micelles are not formed due to concentration of soap, below its CMC value.

Micelle or associate colloid formation occurs above a certain concentration known as CMC. So, if the concentration of soap is less that means it hasn't reached the CMC value. That is why it does not serve the purpose of cleaning of clothes.
