C Correct answer
Explanation

When washing clothes with soap, micelle formation occurs as soap molecules surround oil droplets with hydrophobic tails inside and hydrophilic heads outside. These micelles form a colloidal dispersion in water, allowing oil to be rinsed away. A separate hydrocarbon layer does not form - the oils remain trapped within micelles throughout the washing process.
